Hi Matias,

We should get it into the main SimpleITK repository shortly (after testing etc..). For now please follow D?enan?s recommendation (clone my forked repository, checkout the dicomWrite branch and build SimpleITK from that branch).

     regards
        Ziv

Hi Matias,

you should use branch dicomWrite from Ziv's fork<https://github.com/zivy/SimpleITK/tree/dicomWrite>.

Regards,
D?enan

Hello Matias,

Please take a look at the following github pull request (https://github.com/SimpleITK/SimpleITK/pull/134), this branch should provide the functionality you are looking for. See the Python example script included in the commit for the usage of the DICOM series writing.

     hope this helps

Yes, this is what I would need to migrate to C#:
It basically reads a dicom directory and performs rotation on the volume, then writes the resulting images back to a directory, copying the tags from the original images.

Hello,

Writing correct DICOM continues to be a struggle with SimpleITK and ITK. It is generally recommended to directly use GDCM or DCMTK to write a proper DICOM series.

SimpleITK tries to keep things, well, simple and straight forward. But ITK ties to do some smart things, which get in the way for certain uses with SimpleITK. We are trying to document and develop a nominal set of DICOM output operations that work in SimpleITK.

Do you have working C++ code that works for your intended operation? Can you share a small section of code which does what you expect it C++?

Thank,
Brad

Subject: [ITK] [ITK-users] ITK Python: numpy to itk image (and viceversa)
Message-ID: <50B858FB5F53124F9E32314E5C1B409445967065@MBX212.d.ethz.ch>

Hallo,

I use ITK with Python Wrap. I need to interface my Python code with a Cython-wrapped C++ code that takes only numpy array as input and returns numpy array as output.

Hence, I need to convert the Python itk images into numpy array to be given as input to the wrapped C++ code, and then convert the numpy array in output from the wrapped C++ code back into python itk images.

Question 1) How can I do that in an efficient way? I found some posts on itk.PyBuffer but I could not find anywhere any reference on how to install it on my itk wrap build.

Question 2) The purpose of writing a part of my algorithm in C++ is to speed up the code. If the conversion between python itk images and numpy arrays is slow, I would lose all the speed gain obtained with the C++ implementation. Are there better ways to deal with that?

Thank you,

Fabio.

Hallo Fabio,

Cool. By the way, you may be interested in scikit-build [1], which is
a good way to build Cython-wrapped C++ code. We are using it for the
ITK and SimpleITK Python packages, and it has good Cython and CMake
support.

Yes, itk.PyBuffer works great for that. Please review a PR for some
additional documentation:

  https://github.com/InsightSoftwareConsortium/ITKBridgeNumPy/pull/18

This has been available in ITK for a few releases as a Remote module,
which can be enabled by setting

  Module_BridgeNumPy=ON

in ITK's CMake configuration.


Since ITK 4.11.0, it is easier to build since it does not require the
NumPy headers.


In current ITK Git master (to be 4.12.0) the module is enabled by default.


Nightly ITK Python packages for ITK Git master are now being built:

  https://github.com/InsightSoftwareConsortium/ITKPythonPackage

macOS and Linux are available. Windows packages will be available over
the coming weeks.

The newer versions ITKBridgeNumPy use a NumPy array view, which does
not do any copies during the conversion, and it is very fast.


HTH,
Matt

Thanks! This patch has been uploaded:

  http://review.source.kitware.com/#/c/22149/3


The typos could go in a different patch (ideally), but it is OK, if
they are included.

Thanks,
Matt

Hi Zein,

It sounds like this is ITKv3.  A number of Otsu fixes have been made
in ITKv4 - upgrading will likely fix the issue.

While SolverCrankNicolson can be used for time dependent problems, in
the context of the presentation (Au = f) and the example,

  https://github.com/InsightSoftwareConsortium/ITK/blob/f9110a0046a9d07a921767ba000443ad006a2c9b/Examples/RegistrationITKv4/DeformableRegistration1.cxx#L131

you are correct -- it is not being used for time-dependent problems,
because they are only using a stiffness matrix and not a mass matrix.

https://github.com/InsightSoftwareConsortium/ITK/blob/f9110a0046a9d07a921767ba000443ad006a2c9b/Modules/Numerics/FEM/include/itkFEMSolverCrankNicolson.hxx#L298-L318

To clarify, there are five different registration frameworks within ITK.

1) The Variational Registration framework

2) The ITKv3 Registration framework

3) The ITKv4 Registration framework (classes have "v4" suffix).

4) The PDE deformable registration filters (these include optical flow
algorithms)

5) The FEM Registration

The VariationalRegistrationFilter is from the Variational Registration
framework and is not used by FEM Registration.


It sounds like you are most interested in variational registration,
and the Variational Registration and ITKv4 Registration could help.

Subject: [ITK] Maintenance of the Insight Toolkit
Message-ID: <CALzTN-TLxrO3zk35iyK1E_8c4Eib-SrZe5eTJgKbZSfADTwutA@mail.gmail.com>

Hi folks,

As United States government is re-examines the value of its funding
initiatives, we have an opportunity to explain the value of the
Insight Toolkit (ITK) project, and its associated open science
community.

The National Library of Medicine (NLM) has driven open science and
reproducible research long before the recent surge in popularity of
the movement. Not only did the NLM start the Insight Toolkit project
in 1999, but it has continuously enabled it to thrive by supporting
community development, maintenance, and algorithmic and technological
advances to this day.

Open science needs active communities, supported communities,
standards, open-source tools, strong ties will commercial / clinical
efforts, high-quality practices, transparency, and more - and those
are exactly the strengths of our community's toolkits, applications,
and projects. We should to encourage the NLM (NIH, DHHS, US
Government) to continue to prioritize these efforts via their funding.


To emphasize the impact of this community, please share your story. We
would like to describe outstanding projects and efforts that use the
Insight Toolkit. If you have stories, descriptions, or statistics of
the impact of ITK or projects that leverage it, they justify future
investments in this area.

If you can help, please send a description of your project or your
relationship with the Insight Toolkit for research, industry, or
education to <matt.mccormick at kitware.com> by Tuesday, April 11th.


For example,

Dear US National Library of Medicine,

Thanks you for funding the Insight Toolkit project and supporting its
maintenance and community. For the past two years, the documentation,
software, and community have been a valuable resource for my research
on neurocognitive imaging.

Sincerely,
Alice Insight, PhD
Reproducible University


Thank you,
Matt

Hello Matias,

Ziv's patch was merged into SimpleITK?s master branch yesterday. The CDash builds[1] compiled the update and created binaries which are linked in the golden boxes. I believe you want CSharp for window 64[2].

Enjoy!

Yes, this is what I would need to migrate to C#:
It basically reads a dicom directory and performs rotation on the volume, then writes the resulting images back to a directory, copying the tags from the original images.

Hello,

Writing correct DICOM continues to be a struggle with SimpleITK and ITK. It is generally recommended to directly use GDCM or DCMTK to write a proper DICOM series.

SimpleITK tries to keep things, well, simple and straight forward. But ITK ties to do some smart things, which get in the way for certain uses with SimpleITK. We are trying to document and develop a nominal set of DICOM output operations that work in SimpleITK.

Do you have working C++ code that works for your intended operation? Can you share a small section of code which does what you expect it C++?

Thank,
Brad

Hi Manuel,

I was able to create an import error, and then it was resolved by
adding the directory with the file vtkImagingCorePython35D-7.1.dll to
the PATH environmental variable.

Hope this helps,
Matt

Subject: [ITK] [ITK-dev] Build errors using a different C and CXX compiler
Message-ID: <BB062784844ECF47BDC58DEA5F984A8EAA644E@ORSMSX107.amr.corp.intel.com>

Hi all,

I am attempting to build ITK from source (have tried using v4.11.0 and master) using a different CXX compiler. To start, I do not have an issue when I utilize the default compiler (gcc) as much compiler. This works fine; tests are successful.

The error I encounter on both Ubuntu and Centos systems is the same. It looks like this on the make output:
[ 58%] Building CXX object Modules/Core/ImageFunction/test/CMakeFiles/ITKImageFunctionTestDriver.dir/itkRayCastInterpolateImageFunctionTest.cxx.o
/src/ITK/Modules/Core/ImageFunction/include/itkRayCastInterpolateImageFunction.hxx(38): error: member "<unnamed>::RayCastHelper<TInputImage, TCoordRep>::InputImageDimension [with TInputImage=itk::Image<unsigned char, 3U>, TCoordRep=double]" was referenced but not defined

My cmake setup looks like this:

Does anyone have a pointer to see where this error comes from? Thank you.

Hi Jon,

It does not look like we have working builds of ICC on the dashboard
[1]. As they say, if it not tested, it is broken. There are two x86_64
ICC builds, but they either have a build system issue, or ITK needs to
be updated to use this compiler. What version of the compiler is it?

Thanks,
Matt

Subject: [ITK] [ITK-users] Extract slice from ResampleFilter
Message-ID: <1491482054290-38074.post@n7.nabble.com>

Dear all, 

I am trying to extract density profile along a trajectory in CT. Using some
adjustments to contour-based segmentation and getting a mesh from the binary
mask, I computed certain trajectories tangential to certain faces/vertices
of the mesh. 

Now, I have the coordinates of the target point and a tangent to the target.
So, depending on the spacing, I extract all the points along the tangent
which are 5mm away from the target. I am using following code to generate
densities after I have got the physical coordinates along this line. 

void generateDensities(std::vector<Vector3d> points,
InternalImageType::Pointer image){

	InternalImageType::IndexType pixelIndex;
	PointType point;
	itk::ContinuousIndex<double, Dimension> pixel;	
	linearInterpolationContinuousIndexType::Pointer interpolate =
linearInterpolationContinuousIndexType::New();

	interpolate->SetInputImage(image);

	std::vector<int> HU_values;
	std::vector<double> HU_values_interpolate;
	std::vector<InternalImageType::IndexType> Pixel_indices;
	std::vector<itk::ContinuousIndex&lt;double, Dimension>>
Pixel_indices_interpolated;
	// std::cout << "Generating with interpolation" << std::endl;
	for (int i = 0; i < points.size(); i++)
	{
		Vector3d temp_point = points.at(i);
		point[0] = temp_point[0];
		point[1] = temp_point[1];
		point[2] = temp_point[2];
		// std::cout << "Getting continuous index " << std::endl;
		bool isInside = image->TransformPhysicalPointToContinuousIndex(point,
pixel);
		if (isInside)
		{
			InternalImageType::PixelType pixelValue =
interpolate->EvaluateAtContinuousIndex(pixel);
			HU_values_interpolate.push_back(pixelValue);
			Pixel_indices_interpolated.push_back(pixel);
		}
		else
			std::cout << "Point " << point << " with index " << pixel << "is outside"
<< std::endl;
	}
	All_HU_values_interpolated.push_back(HU_values_interpolate);
	All_pixel_indices_interpolated.push_back(Pixel_indices_interpolated);
	HU_values_interpolate.clear();
	HU_values.clear();
}

Now, for verification that I am actually getting in fact the correct values,
I would like to extract the oblique slice along this trajectory and I figure
I have to use the Resample filter to "transform" the CT so that rotation
puts the resampled CT coordinate system parallel to the trajectory and the
origin translated to the start of the trajectory. Now, along the trajectory,
with the set of collinear points (along the trajectory), I can get a lot of
planes (oblique slices essentially) which have the trajectory in them. So to
get around this, I figure if I give another point which is non-collinear to
these points, I can specify the exact oblique slice I want. However, this is
something I have to figure out for a lot of trajectories for the same CT and
then correspondingly for others. Can someone tell me how can I achieve this
"automatically" for all trajectories/CTs? 
PS. All CTs have the same spacing and origin. 
Kindly also mention if you think the function for generating the densities
is correct or not? Eitherways I would like to validate. 

Thank you,
Sidharta

Thanks Christina for taking care of this problem! The patch you submitted
looks good to me. It would be perfect if you could create a test using the
images your generate to ensure that the problem does not appear again in
the future.

Matt,

I just met with a technical lead for the Intel compiler front-end group to review this issue. I may have uncovered a bug in the front-end logic. They are investigating to dig into the reason for this anomaly. When I receive their analysis, I will report back what the next steps are.

Hi Jon,

It does not look like we have working builds of ICC on the dashboard [1]. As they say, if it not tested, it is broken. There are two x86_64 ICC builds, but they either have a build system issue, or ITK needs to be updated to use this compiler. What version of the compiler is it?

Thanks,
Matt

Message-ID: <CAHE0P1VFC8P9xjhj5sdq-nmyx9KWGBWJoZS75Drmv1CAB0FiQg@mail.gmail.com>

Hello,

Does ITK offer a function to determine whether or not a given file path
corresponds to a DICOM image?

Asking because DICOM standard does not require file names to have a ".dcm"
or any other extension.

Thanks,

Hi Fijoy,

I am not sure about such a function, but you could try reading it using
gdcm reader IO, and if it throws an exception it is not.

D?enan

Hi D?enan,

I just found that itk::GDCMImageIO has a CanReadFile() function. I'll try
that.

Thanks,

There is a confirmed bug in the latest release of the Intel Compiler. Any code which compiles in gcc should compile under icc. There is a workaround listed in the last comment here: https://software.intel.com/en-us/comment/1902247. I will notify once a fix has been released. I will try to find out if we can include ITK in regular build tests for ICC development.

There is a workaround listed in the last comment here: https://software.intel.com/en-us/comment/1902247. I will notify once a fix has been released. I will try to find out if we can include ITK in regular build tests for ICC development.

Hi,

I found that ITK (such as fast-marching level-set, threshold-based level-set, and region growing) does not use all CPU cores during computation. 

My questions include:
1. Does ITK support full CPU cores computation?
2. Did anyone try to speed up ITK? If so, What is the best and fast way to speed up ITK? And how much faster than before can I achieve?

I appreciate any help in advance. Thank you.

Best regards,
Xiaopeng

Subject: [ITK] [ITK-users] Private Tags with itk 4.7 and gdcm
Message-ID: <3890D9E960F85D4FA055392AAA00D285C36A5B@ALPURAPA25.e2k.ad.ge.com>

Hello,
I read some posts about private tags not working properly but couldn't find a way to load private tags.

I'm using DicomSeriesReadPrintTags_8cxx

And I used
dicomIO->LoadPrivateTagsOn()

and
nameGenerator->SetLoadPrivateTags ( true );

But I get values for all private tags as

(0043|10a8)  = MlwtNVwyNSA=

I can view using any tool to see  the value as
(0043|10b2) Private tag data                   LO: ['9548', '162.6', '338.391', '-2.870712']

I wonder shall I need to add this tag in dictionary as well?
I tried playing around with the gdcm dictionary like;
const gdcm::Global &g = gdcm::Global::GetInstance();
const gdcm::Dicts &dicts = g.GetDicts();
const gdcm::Dict & pubdict=dicts.GetPublicDict();

but it doesn't provide any example or any source about how to use private dictionaries or add any tag values in that?
Can some one please help here with some source code about how to resolve this issue with itk 4.7 and gdcm 2.2

Thanks,

Hi Syed,

I think that you need to do base64-decoding. E.g. MlwtNVwyNSA= yields
2\-5\25

Subject: [ITK] [ITK-users] Correct this stereotactic error in a Volume
Message-ID: <1491665590917-38079.post@n7.nabble.com>

Hi,I'm dealing with an image which was captured somewhat incorrectly and I'm
trying to solve or correct the stereotactic frame snake figure so that it
gets as a line.Here's the Volume I'm trying to rectify: Look at the "snake"
figure in the stereotactic oblique stick.
<http://itk-users.7.n7.nabble.com/file/n38079/screenshot.jpg> Is there any
method in ITK to solve this? we did apply a resample (every 1mm) but did not
work. We also rotated the volume using Euler3D and some precalculated angles
(Gamma, Beta,Alfa) and still remained the same.I think is a matter of
rotating every 10 slides or so which is where we see the stereotactic frame
movement in the slides but not sure how to perform this. We thought of
rotating each slide but that doesn't work since it has to rotate the volume.

Subject: [ITK] [ITK-users] Extract slice from ResampleFilter
In-Reply-To: <1491482054290-38074.post@n7.nabble.com>
References: <1491482054290-38074.post@n7.nabble.com>

Hi Sidharta,

your function to calculate interpolated Hounsfield values seems correct.

Your problem of selecting oblique slice to resample can be reduced to
finding a plane which passed through your first and last point, and as an
arbitrary constraint passes through point [0,0,0]. If this point is
collinear with your line then pick point [1,0,0], [0,1,0] or [0,0,1]. One
of them will not be collinear.

In order to resample your oblique slice, you need to figure out a transform
matrix which transforms your first point to coordinates [0,0,0], your last
point to coordinates e.g. [1000,0,0] and transforms the normal of your
plane to be parallel with vector [0,0,1].

Then use resample filter, set your transform matrix and set as target
image's region index [0,0,0] and size [1001,1,1]. Alternatively index
[0,-10,0] and size [1001,21,1] if you want to have a real 2D slice to look
at.

Hope this helps,
D?enan

Message-ID: <1491689302258-38081.post@n7.nabble.com>

Hi,I'm rotating a volume (Using the Euler3DTransform) and the final set of
slices are half black or empty.here's an example when rotating a volume of
10 slices:Am I missing something such as changing the origin or maybe
computing the center incorrectly? (The center is passed as parameter from
another program) <http://itk-users.7.n7.nabble.com/file/n38081/capture.jpg>
And here's the code I'm using:	typedef itk::ResampleImageFilter<ImageType,
ImageType> FilterType;		FilterType::Pointer FiltroResample =
FilterType::New();		FiltroResample->SetInput(reader->GetOutput());		typedef
itk::LinearInterpolateImageFunction<ImageType, double > InterpolatorType;	
InterpolatorType::Pointer interpolator = InterpolatorType::New();	
FiltroResample->SetInterpolator(interpolator);	
FiltroResample->SetOutputDirection(inputImage->GetDirection());	
FiltroResample->SetOutputOrigin(inputImage->GetOrigin());	
ImageType::SizeType inputSize =
inputImage->GetLargestPossibleRegion().GetSize();	
FiltroResample->SetSize(inputSize);		const ImageType::SpacingType&
inputSpacing = inputImage->GetSpacing();	
FiltroResample->SetOutputSpacing(inputSpacing);	
FiltroResample->SetDefaultPixelValue(-1000);		typedef itk::Euler3DTransform<
double > TransformType; //Transform		TransformType::Pointer transform =

atof(argv[2]);		beta = atof(argv[3]);		alfa = atof(argv[4]);	
centro_rotacion_X = atof(argv[5]);		centro_rotacion_Y = atof(argv[6]);	
centro_rotacion_Z = atof(argv[7]);		origenX = atof(argv[8]);		origenY =

Dear insight-users,


I would like to ask, if I could specify the Maximum distance between points after extracting the points using BinaryMaskToNarrowBandPointSetFilter.


Thank you in advance.


Kind regards,

Dear D?enan,

Thank you for your reply. Actually, I found a third point which gives me the
exact (informative) slice I am looking for. Should I resample the image
twice, first rotate the image to the direction of the trajectory and move
the origin to the start of the trajectory and second rotate the image to the
angle between the trajectory and the third point? I will try what you said
and get back to you. I am asking because I don't think resampling twice
makes sense. 

Thank you for your time.
Sidharta

Hello,

Regarding single threaded region growing, the nature of regions growing with a breadth first algorithm is inherently single threaded. However, the equivalent results can be obtained by doing a global threshold, followed by connect components analysis. Both of those algorithms are efficiently multi-threaded. Depending on the size of the image, shape of region, and other factors, one approach may be more efficient than the other.

HTH,
Brad

?Hi Sidharta,

you definitely should not resample twice. All you need is to compound the
two transforms (multiply their matrices)?. And apply a single resampling.
But for debugging purposes, you could also display the resampled output
after only the first transform.

Regards,
D?enan

In the image mask, the parts we want to include in the calculation are
bright and the parts that we want to exclude are dark, is that the opposite

Hello Andrew,

Did you try to initialize the registration with [1] for example?
If the images do not overlap at all at the beginning of the registration,
the algorithm might only do what D?enan said, match black pixels.
Initializing the transform should help.

Hope this helps,
Francois

Subject: [ITK] [ITK-dev] Static link "error LNK2005: png_get_uint_31 already
 defined in png.lib", missing #define in itk_png_mangle.h?
Message-ID: <21acf28759ecc26926c0ac9b01080102@xs4all.nl>

When trying build our project, which links statically to both ITK and 
the Niftyreg library, my colleague Floris Berendsen and I encountered 
the following link error:

   >itkpng-4.10.lib(pngrutil.obj) : error LNK2005: png_get_uint_31 
already defined in png.lib(pngrutil.obj) 
[...\SuperElastix-build\Testing\Unit\selxAnyFileIOTest.vcxproj]
   >...\SuperElastix-build\bin\Debug\selxAnyFileIOTest.exe : fatal error 
LNK1169: one or more multiply defined symbols found 
[...\SuperElastix-build\Testing\Unit\selxAnyFileIOTest.vcxproj]

It appears that ITK and Niftyreg link to different versions of libpng. 
Fortunately, ITK has done name mangling for most of the libpng API 
functions, to avoid such linking errors, as we can see at 
Modules/ThirdParty/PNG/src/itkpng/itk_png_mangle.h  Now it appears that 
the function "png_get_uint_31" is also exported by libpng, but that 
function is not mangled by ITK! We could locally fix our link error by 
adding an extra #define to "itk_png_mangle.h":

     #define png_get_uint_31 itk_png_get_uint_31

Do you guys agree that that would be an appropriate fix? Could such a 
fix be added to the ITK code base?

   Kind regards, Niels

PS Our project, SuperElastix, can be found at 
https://github.com/SuperElastix/SuperElastix  (We tried to build the 
SuperBuild from the development branch.) The Nifty Reg library is from 
https://cmiclab.cs.ucl.ac.uk/mmodat/niftyreg

Hi Niels,

Thanks for discussing the issue. Yes, the addition is a good
improvement that should address the issue. Could you please submit a
patch?:

Hello Niels,

Thank you for reporting this issue. I looked into itk_png_mangle.h and
indeed it looks like the function 'png_get_uint_31' should be renamed and
is not.
Using this command [1], updated to your ITK version, you should be able to
see the the functions that are missing and need to be added to
itk_png_mangle.h .
It would be great if you commit submit a patch to ITK to correct this issue.
You can find step by step instructions about how to contribute here [2].
Feel free to reach out if you have any problem during this process.

Thank you so much for your help,
Francois

Hey D?enan,

So, I kind of got the equation of the plane and the normal to the plane
where all the three non-collinear points lie. Then, I got the angle between
this normal and the z-axis of the image. I resample the image by rotating in
3D about the z-axis. How do I extract the exact slice from the resampled
image? Is it actually required to resample the 3D Dicom, can I not resample
a 2D image (just for optimization purposes)? I read the documentation
(ITKSoftwareGuide) which shows one example for 3D resampling, however not
how to save a particular slice. Kindly correct me if I am wrong. 


Thank you for your time.
Best Regards,
Sidharta

Hello Francois and D?enan,

Because of the way the images were captured, there is a known common point
of overlap, so we set the centre to that point in the expectation that the
transform would rotate and translate about that point when the registration
is run.  Have I misunderstood the design or is that what should be
happening?

Hi Sidartha,

you can use extract filter
<https://itk.org/Doxygen/html/classitk_1_1ExtractImageFilter.html> to
extract a single slice from a 3D image. Take a look at the examples liked
from the documentation page.

Regards,
D?enan

Hi Andrew,

it is good to use such additional constraints when possible. But you also
have to initialize the transform somehow, otherwise it might get
auto-initialized to all modifiable parameters being equal to zero. That is
usually a bad initial transform - hence Francois' suggestion.

Hello Andrew,

Another thing you can look at is if your transform parameters ratios are
set to reasonable values. You typically have a ratio you can set between
rotation, translation, scaling. If these are not set to appropriate values,
the final transform could be wrong.
In your case, it sounds like you are already performing the translation as
an initialization. Maybe you can modify your parameters so that it performs
mostly a rotation.

Hope this helps,
Fran?ois

Subject: [ITK] [ITK-users] Transforming a point
Message-ID: <CACDHZEQUAsT-oqbcVqDCnEP2Nqz2ttY5_-KbJur80P_x=B_bcA@mail.gmail.com>

Hi,

  I have a affine transformation matrix with a set of points as fixed
landmarks and moving landmarks. I was trying to verify the transformation
by using the transform point method in the transformation class,ideally i
should get back the fixed points when i give the moving points as input ,
but I am not getting it as the output.  The code which i used is as below:

typedef itk::AffineTransform<double,3> AffineTransformType;
AffineTransformType::Pointer transf;

transf = dynamic_cast<AffineTransformType*>( transfm.GetPointer() );
typedef itk::Similarity3DTransform<double> SimilarityTransformType;
SimilarityTransformType::Pointer transform = SimilarityTransformType::New();

typedef itk::LandmarkBasedTransformInitializer< SimilarityTransformType,
InputImageType, InputImageType >
LandmarkBasedTransformInitializerType;
   LandmarkBasedTransformInitializerType::Pointer
landmarkBasedTransformInitializer =
   LandmarkBasedTransformInitializerType::New();

   typedef LandmarkBasedTransformInitializerType::LandmarkPointContainer
  LandmarkContainerType;
   typedef LandmarkBasedTransformInitializerType::LandmarkPointType
 LandmarkPointType;

   LandmarkContainerType movingLandmarks;

   LandmarkPointType movingPoint;

   double *ptrf_moving_point = ptf_moving_landmark_pointslist;
   for(int

Hi D?enan,

Of course I would use that (sorry for not mentioning it that I know this
already), but how do I get this particular plane (2D slice)? I don't want to
hard code anything.

Hope you understand 
Thank you for your time
Sidharta

Hello Sidharta,

You can use the filter called ExtractImageFilter [1]. You should be able to
achieve your goal with that.
Hope this helps,

Francois

Hi Sidharta,

to get the particular plane you want, set up the transform in such a way
that that slice gets transformed to some know spatial position (e.g. your
first point to coordinates [0,0,0] and your last point to coordinates
[1000,0,0]). Then you only need to resample your volume to a 3D image of
thickness 1 slice which passes through points [0,0,0] and [1000,0,0]. You
don't even need extract filter with this approach.

D?enan Zuki?, PhD, Senior R&D Engineer, Kitware (Carrboro, N.C.)

Hello Swetha,

In general, the transformations computed using the ITK registration framework are from the fixed coordinate system to the moving coordinate system. Thus, the transformation should be applied as T(point_fixed) = point_moving.

I did not read your code so I may be missing something specific to your work, but this mapping is something that many newcomers to ITK seem to get confused with.

     hope this helps

Subject: [ITK] [ITK-users] Transforming a point

Hi,

  I have a affine transformation matrix with a set of points as fixed landmarks and moving landmarks. I was trying to verify the transformation by using the transform point method in the transformation class,ideally i should get back the fixed points when i give the moving points as input , but I am not getting it as the output.  The code which i used is as below:

typedef itk::AffineTransform<double,3> AffineTransformType;
AffineTransformType::Pointer transf;

transf = dynamic_cast<AffineTransformType*>( transfm.GetPointer() );
typedef itk::Similarity3DTransform<double> SimilarityTransformType;
SimilarityTransformType::Pointer transform = SimilarityTransformType::New();

typedef itk::LandmarkBasedTransformInitializer< SimilarityTransformType, InputImageType, InputImageType >
LandmarkBasedTransformInitializerType;
   LandmarkBasedTransformInitializerType::Pointer landmarkBasedTransformInitializer =
   LandmarkBasedTransformInitializerType::New();

   typedef LandmarkBasedTransformInitializerType::LandmarkPointContainer     LandmarkContainerType;
   typedef LandmarkBasedTransformInitializerType::LandmarkPointType          LandmarkPointType;

   LandmarkContainerType movingLandmarks;

   LandmarkPointType movingPoint;

   double *ptrf_moving_point = ptf_moving_landmark_pointslist;
   for(int iPointIndex=0;iPointIndex<iNumberofLandMarkPoints_moving;iPointIndex++){
   movingPoint[0] = (*( ptrf_moving_point )) ;
movingPoint[1] = (*( ptrf_moving_point + 1));
movingPoint[2] = (*( ptrf_moving_point + 2));
movingLandmarks.push_back( movingPoint );
ptrf_moving_point = ptrf_moving_point + 3;
   }

   typedef itk::PointSet< double, 3 >   PointSetType;
   PointSetType::Pointer registeredPointSet = PointSetType::New();
   typedef PointSetType::PointType     PointType;
   PointType registeredPoint;
   typedef PointSetType::PointsContainer  PointsContainer;
   PointsContainer::Pointer registeredPointContainer = PointsContainer::New();

   for(int i=0;i<movingLandmarks.size();i++){
  registeredPoint =   transf->TransformPoint( movingLandmarks[i] );
       registeredPointContainer->InsertElement( i, registeredPoint );
   }

   registeredPointSet->SetPoints(registeredPointContainer);

//Write the registered pointset into file
std::ofstream   registeredFile;
registeredFile.open( "registered_points.txt");
if( registeredFile.fail() )
{
  return -1;
}
for( int i = 0; i<registeredPointSet->GetNumberOfPoints(); i++)
{
  registeredPointSet->GetPoint( i, & registeredPoint );
  for(int j = 0; j<3; j++)
  {
   registeredFile<<registeredPoint[j]<<"\t";
  }
  registeredFile<<"\n";
}

 Is there a mistake in the code ?How do I transform the points?

Thank you. I am trying to build ITK Wrap Python with Module_BridgeNumPy=ON with Visual Studio 2017.

I get the following type of errors:

The build worked with Visual Studio 2015 instead.

Can I fix this issue with Visual Studio 2017 somehow?

Thank you.

Cool. By the way, you may be interested in scikit-build [1], which is a good way to build Cython-wrapped C++ code. We are using it for the ITK and SimpleITK Python packages, and it has good Cython and CMake support.

Yes, itk.PyBuffer works great for that. Please review a PR for some additional documentation:

  https://github.com/InsightSoftwareConsortium/ITKBridgeNumPy/pull/18

This has been available in ITK for a few releases as a Remote module, which can be enabled by setting

  Module_BridgeNumPy=ON

in ITK's CMake configuration.


Since ITK 4.11.0, it is easier to build since it does not require the NumPy headers.


In current ITK Git master (to be 4.12.0) the module is enabled by default.


Nightly ITK Python packages for ITK Git master are now being built:

  https://github.com/InsightSoftwareConsortium/ITKPythonPackage

macOS and Linux are available. Windows packages will be available over the coming weeks.

The newer versions ITKBridgeNumPy use a NumPy array view, which does not do any copies during the conversion, and it is very fast.


HTH,
Matt

Hi Fabio,

let me give it a try with VS2017 and Wrapping+NumPy. I will report back when I have an update.

The build worked with Visual Studio 2015 instead.

Can I fix this issue with Visual Studio 2017 somehow?

Thank you.

Cool. By the way, you may be interested in scikit-build [1], which is a good way to build Cython-wrapped C++ code. We are using it for the ITK and SimpleITK Python packages, and it has good Cython and CMake support.

Yes, itk.PyBuffer works great for that. Please review a PR for some additional documentation:

  https://github.com/InsightSoftwareConsortium/ITKBridgeNumPy/pull/18

This has been available in ITK for a few releases as a Remote module, which can be enabled by setting

  Module_BridgeNumPy=ON

in ITK's CMake configuration.


Since ITK 4.11.0, it is easier to build since it does not require the NumPy headers.


In current ITK Git master (to be 4.12.0) the module is enabled by default.


Nightly ITK Python packages for ITK Git master are now being built:

  https://github.com/InsightSoftwareConsortium/ITKPythonPackage

macOS and Linux are available. Windows packages will be available over the coming weeks.

The newer versions ITKBridgeNumPy use a NumPy array view, which does not do any copies during the conversion, and it is very fast.

Fabio,

To add a little bit of extra information about using BridgeNumpy:

>From NumPy to ITK, the memory is never copied, and always shared between
the NumPy array and the ITK image.
>From ITK to NumPy, the memory is not copied at first, if the data is not
changed from the NumPy side (e.g. if the ITK image is changed, the NumPy
array will be modified too), but if you modify the NumPy array directly,
NumPy will create a copy of the data. This also means that if you were to
modify the NumPy array, the modifications would not be visible in the ITK
image.

A limited workaround to this is:

# Get NumPy array from image
arr_image = itk.GetArrayFromImage(image)
# Create copy of array that can be modified in-place
arr = arr_image.copy()
# Modify array
?
# Update image in-place with new array
arr_image.setfield(arr,arr_image.dtype)

The advantage of this method is that the image will be updated. However,
there is an explicit copy of your data.
If the copy step is skipped and the original NumPy array is modified, a
copy of the data will be performed by NumPy and you may not be aware of it
until you see that the data in the NumPy array and the image do not match
anymore.

Hope this helps,
Francois

Hi Fabio,

it looks like we will have to wait somewhat until VS writers get around to
implement __builtin_offsetof
<https://developercommunity.visualstudio.com/content/problem/22196/static-assert-cannot-compile-constexprs-method-tha.html>

I don't know why it doesn't trigger when Python wrapping is OFF. I will
look into it more.

D?enan Zuki?, PhD, Senior R&D Engineer, Kitware (Carrboro, N.C.)

Subject: [ITK] [ITK-users] HistogramEqualization in ITK
Message-ID: <1492086337666-38108.post@n7.nabble.com>

Dear all
  I want to use itk::AdaptiveHistogramEqualizationImageFilter to do a
HistogramEqualization filter on a image as follow:
<http://itk-users.7.n7.nabble.com/file/n38108/snipaste20170413_200959.png> 
So I set the parameters SetAlpha(0.5), SetBeta(0.5), the result is as
follow:
<http://itk-users.7.n7.nabble.com/file/n38108/snipaste20170413_201446.png> 
but actually the result I want is showed as follow (which is generated by
opencv cvEqualizeHist() function):
<http://itk-users.7.n7.nabble.com/file/n38108/snipaste20170413_201132.png> 
So I want to ask you if I can get that HistogramEqualization result by ITK?

Thanks a lot
Wang

Hello,

You need to read and study the two algorithms closer. There is a referenced paper in the ITK documentation[1].

You should also look into the HistogramMatchingImageFilter [2].

HTH,
Brad

Hi D?enan,

So I am doing something as follows: 

// Vectors for calculating normal_to_plane - The plane/slice I want to
extract

Vector3d ST, SP, normal_to_plane; // This is a custom 3D Vector library
ST = traj_start - traj_end; // start and end of the trajectory - vector 1
SP = traj_start - third_point; // start and third point gives another vector
- vector 2
// Now with two vectors I can get the direction of the normal to the plane
normal_to_plane = ST.cross(SP); // cross product essentially

// Getting angles between normal to the plane and the coordinate axes
double angle_plane_z = std::acos((normal_to_plane[2] * 1) /
norm(normal_to_plane)); // angle between plane and z axis
double angle_plane_y = std::acos((normal_to_plane[1] * 1) /
norm(normal_to_plane)); // angle between plane and y axis
double angle_plane_x = std::acos((normal_to_plane[0] * 1) /
norm(normal_to_plane)); // angle between plane and x axis

// Instantiate an Euler Transform
typedef itk::Euler3DTransform<double> ETransformType;
ETransformType::Pointer eulerTransform = ETransformType::New();

// This because - Quote from ITKSoftwareGuide "Rotations are performed
around the origin of physical coordinates?not the image origin nor the image
center"
ETransformType::OutputVectorType translation1;
translation1[0] = -origin_dcm[0]; // origin_dcm is the origin of the dicom
translation1[1] = -origin_dcm[1]; 
translation1[2] = -origin_dcm[2];
eulerTransform->Translate(translation1);
eulerTransform->SetRotation(angle_plane_x, angle_plane_y, angle_plane_z);

// Get back to the origin of the dicom
ETransformType::OutputVectorType translation2;
translation2[0] = origin_dcm[0];
translation2[1] = origin_dcm[1];
translation2[2] = origin_dcm[2];

// Instantiate the ResampleFilter
// typedef double InternalPixelType;
// typedef itk::Image< InternalPixelType, Dimension > InternalImageType; //
For clarity
typedef itk::ResampleImageFilter<InternalImageType, InternalImageType>
ResampleFilterType;

ResampleFilterType::Pointer filter = ResampleFilterType::New();

typedef itk::NearestNeighborInterpolateImageFunction<
		InternalImageType, double> InterpolatorType;
InterpolatorType::Pointer interpolator = InterpolatorType::New();
filter->SetInterpolator(interpolator);

filter->SetDefaultPixelValue(0);
filter->SetOutputSpacing(image->GetSpacing());
filter->SetOutputOrigin(image->GetOrigin()); // If I change this to
traj_start, the dicom looks completely off, as in not intended.
filter->SetOutputDirection(image->GetDirection()); // I have my doubts about
this too
filter->SetSize(image->GetSize()); // Of course, as you suggested, I would
set the thickness here as 1, but I was doing this for testing purposes.
filter->SetInput(image);

So, what do you think about this code? Am I doing it correctly? I feel
really dumb asking you to check my code but unfortunately I can't find any
relevant example for 3D resampling. Additionally, (no offense) but I don't
get what you mean by "target region index" with respect to the resampling
filter? Do you mean the SetOrigin()? As you also see, I am essentially not
applying any translation to the origin. Just a rotation for testing
purposes.

Thank you for your time.
Best Regards,
Sidharta

Hello Wang,

One good way to explore the parameters to figure out which set gives you
the result you want would be to write a short Python script:
reader=itk.ImageFileReader[itk.Image[itk.UC,2]].New(FileName="/home/fbudin/Downloads/chest.png")
myFilter=itk.AdaptiveHistogramEqualizationImageFilter.New(reader)
for alpha in range(0,11):
  for beta in range(0,11):
    myFilter.SetAlpha(alpha*.1)
    myFilter.SetBeta(beta*.1)
    filename="/tmp/myFilter"+str(alpha)+"_"+str(beta)+".png"
    itk.ImageFileWriter.New(hm,FileName=filename).Update()

I was not able to generate an image that looked exactly like the "opencv"
image you sent, but that may be due to:
-The implementation of this algorithm in OpenCV is different
-The difference of the output is only due to different visualization
parameters (Window/Level settings that are different for the different
images).

Hope this helps,
Francois

Hi Sidartha,

the code looks OK. The index is [0,0,0] by default, so just setting size is
enough. My idea was not to apply translation2, then you would not have to
set origin on the resample filter (it would start from [0,0,0]).

I think you are forgetting to apply second translation, and you are not
applying any transformation to the resample filter. Something like this is
needed:
filter->SetTransform(eulerTransform);

What results are you getting?

D?enan Zuki?, PhD, Senior R&D Engineer, Kitware (Carrboro, N.C.)

Hi Fabio,

the first error is coming from ITKCommonCastXML project, and the other
first 1000 errors are also coming from*CastXML and *Swig projects. This
means that the wrapping infrastructure is somehow triggering that bug in
VS2017.

The easiest thing to try is update CastXML, which Matt said would take care
of. Let's see if that helps.

Hi  D?enan,

Sorry about that, I missed the line in the post. I am, in fact, adding that
line filter->SetTransform(). 

Apologies, but I don't know how I can share .dcm/.mhd image. I am just going
to add the desirable which I did using Amira, which is where I got the idea
of using EulerTransform. 
<http://itk-users.7.n7.nabble.com/file/n38115/snapshot.jpg> . The big sphere
is the third point and the two small ones are the start and end of the
trajectory. The slices on the bounding box are essentially on the origin.
So, with vector math I could get the equation of the plane and so forth. If
you want to see the output .dcm, kindly let me know how I can share it with
you ( from a cloud probably but I don't know what you prefer).

Thank you for your swift reply and patience.

Regards,
Sidharta

Hi Matias,

you are not using origenX or origenY after they are defined. But your
program (with modifications to make it compile) works for me:

?Hi Siddartha,

you can share using cloud tools, e.g. Dropbox or Google Drive.

But I think you forgot to ask the question: I don't know what you are
asking.

So if you think the code is correct and is doing what you suggested (or what
I think it should do using the eulerTransform), you mentioned setting
targetRegionIndex in ResampleFilter to get one single slice. I don't see
this targetRegionIndex or do you mean set origin. I am going to send you the
link to the dropbox folder in a private mail.

The target region is the region (index and size) you set in the resample
filter. It is just a difference in terminology between you and me.

I took a look at the images you supplied. Because of transformations, this
is hard to debug.

I realized it would be easier to construct the output image to be in the
same physical space as the input image, and have identity transform applied
to resample filter (used by default). Pseudo-code:

ImageType::DirectionType dir;
ST.normalize();
dir[0]=ST; //vector from first point to second
vec3 second=normal.cross(ST); //make the second vector orthogonal to first
and the normal
second.normalize();
dir[1]=second;
normal.normalize();
dir[2]=normal;
filter->SetOutputDirection(dir);
filter->SetOrigin(traj_start);
//it will be more math to compute proper size (so that resampled image ends
at traj_end), and proper spacing (project original spacing onto coordinate
system established by new dir matrix or use isotropic spacing equal to
cubic root of sp[0]*sp[1]*sp[2]).

With this approach you can use e.g. Slicer <https://www.slicer.org/> to
look at both the original and resampled images, and also define fiducial
points for your 3 points of interest.

P.S. If you share any more images, please save them with compression
applied (writer->SetUseCompression(true);).

Message-ID: <BB062784844ECF47BDC58DEA5F984A8EAAEBA3@ORSMSX107.amr.corp.intel.com>

Hi all,

I recently caught up with Intel's TBB team. There is good news regarding better support for cmake and TBB. Sometime soon, there will likely be a release of TBB to support this need. I will send an update when I have more specific details to pass along.

Subject: [ITK] [ANN] SimpleITK 1.0.0 Release
Message-ID: <3A9B6734-7719-4069-8E7B-E0F1B35A0A5F@mail.nih.gov>

The SimpleITK Development Team and the Insight Software Consortium are proud to announce the first major release of SimpleITK.

SimpleITK is a simplified multi-language interface to the National Library of Medicine?s Insight Segmentation and Registration Toolkit (ITK). Providing an easy to use interface to ITK.

SimpleITK is intended to broaden the use of ITK to researchers and domain scientist who are novice software developers, enabling them to benefit from the image-analysis power of ITK. For experienced software developers, the toolkit enables rapid prototyping of image segmentation and registration frameworks and facilitates evaluation of the effects algorithmic parameter settings have on results with minimal programming effort. In the educational setting SimpleITK's concise interface allows students to experiment with well known algorithms, enhancing their understanding of algorithm performance without the need for advanced software engineering skills.

The toolkit development process follows best software engineering practices including code reviews and continuous integration testing, with results displayed online allowing everyone to gauge the status of the current code and any code that is under consideration for incorporation into the toolkit. User support is available through a dedicated mailing list and the project?s Wiki.
SimpleITK is available for the following programing languages: Python, R, Java, C#, C++, Lua, Ruby, and TCL. Binary versions of the toolkit are available for the GNU Linux, Apple OS X, and Microsoft Windows operating systems. All of the source code is freely available on github under an Apache-2.0 license.

Hi Matias,

I didn't compile to use with Slicer. I only open the input and output image
in Slicer to visualize them.

But making a Slicer CLI module is fairly easy. You can take a look at one
<https://github.com/Slicer/Slicer/tree/master/Modules/CLI/AddScalarVolumes/>
of the existing modules, docs
<https://www.slicer.org/wiki/Documentation/Nightly/Developers/Modules>
including
extension wizard
<https://www.slicer.org/wiki/Documentation/Nightly/Developers/ExtensionWizard>
.

Regards,
D?enan Zuki?, PhD, Senior R&D Engineer, Kitware (Carrboro, N.C.)

Dzenan,
The center of rotation is set to use milimeters or image coordinates?
Thanks

Hi Matias,

center of rotation should use physical units (millimeters).

Subject: [ITK] [ITK-users] Euler3DTransform not taking user defined Center
	of	Rotation?
Message-ID: <1492470714966-38126.post@n7.nabble.com>

Hi,I'm trying to rotate a volume and use an user defined center but no matter
what value I set, it seems the rotation is always performed using the same
center (not sure which, maybe a default center)?Here's the code I'm using..
am I missing something?	typedef itk::Euler3DTransform< double >
TransformType; //Transform		TransformType::Pointer transform =
TransformType::New();		double alfa, beta, gamma, centro_rotacion_X,
centro_rotacion_Y, centro_rotacion_Z, origenX,origenY;		gamma =
atof(argv[2]);		beta = atof(argv[3]);		alfa = atof(argv[4]);	
centro_rotacion_X = atof(argv[5]);		centro_rotacion_Y = atof(argv[6]);	
centro_rotacion_Z = atof(argv[7]);		double centro[3] = { centro_rotacion_X,
centro_rotacion_Y, centro_rotacion_Z }; 		transform->SetCenter(centro);			
transform->SetRotation(gamma, beta, alfa);

Hello Matias,

I used the Euler3DTransform in a python terminal to see if I had problems
setting the center and the angle, and everything seems to work as expected:

trans=itk.Euler3DTransform.D.New()
trans.SetCenter([0,0,0])
trans.SetRotation(10,0,0)
trans.TransformPoint([0,0,0])
Out[46]: itkPointD3 ([0, 0, 0])  <-expected as the transform center is
[0,0,0]

trans.SetCenter([10,0,0])
trans.TransformPoint([0,0,0])
Out[48]: itkPointD3 ([5.16482, -7.96596, 3.62828]) <-rotation not around
[0,0,0] but around [10,0,0]

To try to understand you problem, I would advise you to print the content
of your transform to see if it is set as you expect. In my case, I get:

Euler3DTransform (0x18da8a0)

Hope this helps,

Dear Users,

Have anyone tried to convert ITKFastMarchingImageFilter from single thread to multithread?

What is the best way to implement multithreading to that filter? Thank you.

Best regards,
Xiaopeng

Hi D?enan,

Thank you for your reply. I implemented this, and learned some cool stuff in
3DSlicer (in order to compare the two images) but as you said, the size is
difficult to compute. When I set the origin explicitly, to the start of the
trajectory, the resampled image looks good in the direction I want it to be
in, however, lot of information is lost. After putting my head into it for
the past two weeks, I realized there are other ways to achieve I want this
too. Does it make sense to you that I construct another 2D image (or 3D with
thickness 1) by essentially copying the voxel values at the trajectory
points and around it (probably the size equal to the dimensions of the
original image in the x,y direction)? The aim ultimately is in fact to get
one slice which best represents the HU values. I apologize for asking such
silly questions.

Just putting the code of what I did, let me know if it is in fact what you
suggested me to do:

Vector3d ST, SP, normal_to_plane;
	ST = traj_end - traj_start;
	SP = third_point - traj_start;
	normal_to_plane = ST.cross(SP);
	std::cout << "Vector ST : " << ST << " Vector SP : " << SP << " Direction
of normal : " << normal_to_plane << std::endl;

	InternalImageType::DirectionType dir;
	// vector from start to the end of the trajectory 
	Vector3d normalized_ST = ST.normalized();
	dir[0][0] = normalized_ST[0];
	dir[0][1] = normalized_ST[1];
	dir[0][2] = normalized_ST[2];

	Vector3d second = normal_to_plane.cross(ST);
	Vector3d normalized_second = second.normalized();
	dir[1][0] = normalized_second[0];
	dir[1][1] = normalized_second[1];
	dir[1][2] = normalized_second[2];

	Vector3d normalized_normal = normal_to_plane.normalized();
	dir[2][0] = normalized_normal[0];
	dir[2][1] = normalized_normal[1];
	dir[2][2] = normalized_normal[2];

	// traj_start += normalized_second * 10;
	double mpr_start[3] = { traj_start[0]  , traj_start[1] , traj_start[2]};

	std::cout << "Previous image direction " << image->GetDirection() <<
std::endl;
	std::cout << "New Image Direction " << dir << std::endl;

	getSliceMPR(image, mpr_start, dir);

void getSliceMPR(InternalImageType::Pointer &image, double
output_origin[Dimension], InternalImageType::DirectionType dir)
{

	// Instantiate Resample Filter here
	ResampleFilterType::Pointer filter = ResampleFilterType::New();
	// Instantiate Transform for resampling
	// Changing the Output direction instead of setting the transform
	// filter->SetTransform(transform);

	typedef itk::NearestNeighborInterpolateImageFunction<
		InternalImageType, double> InterpolatorType;

	// Instantiate the interpolator
	InterpolatorType::Pointer interpolator = InterpolatorType::New();
	filter->SetInterpolator(interpolator);

	// Set pixels of the output image that end up being mapped outside the
extent of the input image to -1500
	filter->SetDefaultPixelValue(-1500);

	// Sampling grid of the output space - pixel spacing in mm
	// Hard coded here
	filter->SetOutputSpacing(image->GetSpacing());


    // filter->SetOutputOrigin(image->GetOrigin());
	
	filter->SetOutputOrigin(output_origin);
	filter->SetOutputDirection(dir);
	InternalImageType::SizeType size;
	filter->SetSize(image->GetLargestPossibleRegion().GetSize());

	filter->SetInput(image);

	typedef itk::ImageFileWriter<InternalImageType> WriterType;
	
	WriterType::Pointer writer = WriterType::New();
	writer->SetFileName("C:/Users/api/Desktop/Resampled/resampled_2.mhd");
	writer->SetUseCompression(true);
	writer->SetInput(filter->GetOutput());
	try{
		writer->Update();

	}
	catch (itk::ExceptionObject & excep){

		std::cerr << "Exception catched!.." << std::endl;
		std::cerr << excep << std::endl;
	}

}

Subject: [ITK] Python Wrapping with no Image Module
Message-ID: <CA+TMiUso_ZHpr7vrMwKP=EyknPKQsMcAhmWE=Xe6dMGCmqw1XQ@mail.gmail.com>

I built the ITK with Python Wrapper in 64 bits in Release mode, using the
python 2.7 and Visual Studio Community 2015, with no errors.
I copy the files and folders generate in Install/lib/site-packages to
C:\Python27\Lib\site-packages.
I use in python import itk and seems to be ok. But I'm not finding the
module Image, like itk.Image
I don't know if it was not generate or where is it. In python just show the
module below.
Someone could help me?

Hi Sidharta,

you seem to have implemented what I suggested.

"essentially copying the voxel values at the trajectory points and around
it" can be achieved by using nearest neighbor interpolator instead of
linear interpolator. But it looks like you are already using nearest
neighbor, so you should try using linear interpolator, or even windowed sinc
<https://itk.org/Doxygen/html/classitk_1_1WindowedSincInterpolateImageFunction.html>
interpolator to get higher quality.

Thanks Francois,

There's something strange in the matrix and Offset, this is what I get:

Center:

[-246.422, -149.871, 20]

Matrix:
1 0 0
0 1 0
0 0 1

Offset:
[0, 0, 0]

Hello Matias,

I created a small executable based on the code you sent me:

#include <itkEuler3DTransform.h>

int main(int argc, char* argv[])
{
  typedef itk::Euler3DTransform< double > TransformType;
//Transform
  TransformType::Pointer transform = TransformType::New();
double alfa, beta, gamma, centro_rotacion_X, centro_rotacion_Y,
centro_rotacion_Z, origenX,origenY;
gamma = atof(argv[2]);
beta = atof(argv[3]);
alfa = atof(argv[4]);
centro_rotacion_X = atof(argv[5]);
centro_rotacion_Y = atof(argv[6]);
centro_rotacion_Z = atof(argv[7]);
double centro[3] = { centro_rotacion_X, centro_rotacion_Y,
centro_rotacion_Z };
transform->SetCenter(centro);
transform->SetRotation(gamma, beta, alfa);
std::cout<<transform->GetCenter()<<std::endl;
std::cout<<transform->GetMatrix()<<std::endl;
std::cout<<transform<<std::endl;
  return 0;
}

And the results are correct:

Subject: [ITK] Python Wrapping with no Image Module
In-Reply-To: <CA+TMiUso_ZHpr7vrMwKP=EyknPKQsMcAhmWE=Xe6dMGCmqw1XQ@mail.gmail.com>
References: <CA+TMiUso_ZHpr7vrMwKP=EyknPKQsMcAhmWE=Xe6dMGCmqw1XQ@mail.gmail.com>

Hi Tenysson,

Welcome to ITK!


The ITK Python wrapping uses lazy loading by default (this increases
interactive loading speed). What we see there is only the ITK modules
and a few special functions. If you are using the IPython terminal
[1], once the tab is pressed for completion, it will load all the
modules. When used in a script, only the modules that are required are
loaded as needed. To force load all the modules and see all the
classes available, call

  itk.force_load()


We have beta Python packages, including binary packages for Python 2.7
on Windows. These may be worth a try because they are built with the
same Visual Studio compiler as the compiler used to build the
python.org distributions, which ensures C runtime compatibility. They
can be installed with:

 python -m pip install --upgrade pip
 python -m pip install itk -f
https://github.com/InsightSoftwareConsortium/ITKPythonPackage/releases/tag/latest

Thanks,
Matt

Hi Matias,

translation (called offset in some of the classes) and center of rotation
are different things, and taken care of differently.

Hi Fabio,

I just tested the master branch after CastXML was updated. Unfortunately,
it didn't help. The compile errors are still present in VS2017 with
wrapping.

Ok, I figured I was calling getmatrix and getoffset before the SetRotation
function.. Now it works well:
Centro:

[-246.422, -149.871, 20]

0.999686 0.0131081 0.0213481
-0.0131859 0.999907 0.00350517
-0.0213002 -0.00378556 0.999766

[1.46023, -3.33334, -5.8115]

I will check with different centers to see if the matrix changes

Thank you for the update. The matrix should change when you update the
center as setting the center calls the function to recompute the matrix.

	testing!
Message-ID: <CALzTN-Sjc0BDQn_291i+V67BJsz5RGN4v5rk7F8aQ+R72uoVMg@mail.gmail.com>

Hi folks,

We now have binary ITK Python packages available for testing! To install,
run

  python -m pip install --upgrade pip
  python -m pip install itk -f
https://github.com/InsightSoftwareConsortium/ITKPythonPackage/releases/tag/latest

These are beta packages that are created on a daily basis. We have packages
for Linux, macOSX, and Windows for Python 2.7, 3.5, and 3.6, along with
source distributions (sdist's). Please share your experiences with these
packages. Initial testing suggests that these packages work both with
system Python distributions, Python distributions downloaded from python.org,
and Anaconda Python distributions.

Thanks,
Matt

Message-ID: <DM5PR06MB265064EEE0CFE64104136C64AD1D0@DM5PR06MB2650.namprd06.prod.outlook.com>

Hello All,


I am working on a Code which is using an iterator which access pixels beyond the region boundary. However, this is not causing an error as I would expect it to. I need to use version 4.0  for legacy reasons. I am attaching a verifiable code and its output with this issue. Let me know if this is a bug in my ITK version or I am missing something and this is correct behavior.


#include "itkImage.h"
#include "itkImageRegionIterator.h"
#include "itkVersion.h"
int main( int argc, char * argv[] )
{
        typedef    float    InputPixelType;
        typedef itk::Image< InputPixelType,  3 >   InputImageType;

        InputImageType::Pointer ip=InputImageType::New();
        InputPixelType *input;
        InputImageType::RegionType region,region1;
        InputImageType::SizeType size,size1;
        InputImageType::IndexType index,index1;
        size[0]=5;
        size[1]=5;
        size[2]=5;
        index[0]=0;
        index[1]=0;
        index[2]=0;

        region.SetSize(size);
        region.SetIndex(index);
        std::cout<<region;
        ip->SetRegions(region);
        ip->Allocate();
        size[2]=1;
        region.SetSize(size);
        std::cout<<region;
        typedef itk::ImageRegionIterator<InputImageType> Iteratortype;
        Iteratortype It(ip,region);
        int count=0;
        for(It.GoToBegin();count<25*5;count++,++It)
        {
                It.Set(27);
        }
        input=ip->GetBufferPointer();
        for(int k=0;k<5;k++)
        {
                for(int i=0;i<5;i++)
                {
                        for(int j=0;j<5;j++)
                        {
                                std::cout<<input[k*25+j+5*i]<<" ";
                        }
                        std::cout<<"\n";

                }
                std::cout<<"\n";
        }
        itk::Version *Ver=itk::Version::New();
        std::cout<<Ver->GetITKMajorVersion()<<"."<<Ver->GetITKMinorVersion()<<"\n";



        return EXIT_SUCCESS;

So, here the code.
You need an image and a label. The calculation of the texture will be into
the label. You normally have to preprocess the image to a specific number
of greylevel, usualy 256 for CT, 64 for PET...
They can be adjusted with maxValue and minValue. MaxVolume is the maximal
volume in number of voxel that you expect a zone will have, if you don't
now just use the volume of the lesion but it can be process consuming.
Also i crop the image and the label before starting the analyse to spare
some ressource. It's a small part f a big program so i hope i didn't forget
any part.

Tell me if you have problem with it or see an error in the code.

Thank you Matt,

I am looking now at scikit-build. 

Do you think I can use it to build C++/CUDA accelerated codes that use ITK too?

Is there a link to a simple example of how to setup a scikit-build for an ITK-based C++ code?

Thank you,
Fabio.

Cool. By the way, you may be interested in scikit-build [1], which is a good way to build Cython-wrapped C++ code. We are using it for the ITK and SimpleITK Python packages, and it has good Cython and CMake support.

Yes, itk.PyBuffer works great for that. Please review a PR for some additional documentation:

  https://github.com/InsightSoftwareConsortium/ITKBridgeNumPy/pull/18

This has been available in ITK for a few releases as a Remote module, which can be enabled by setting

  Module_BridgeNumPy=ON

in ITK's CMake configuration.


Since ITK 4.11.0, it is easier to build since it does not require the NumPy headers.


In current ITK Git master (to be 4.12.0) the module is enabled by default.


Nightly ITK Python packages for ITK Git master are now being built:

  https://github.com/InsightSoftwareConsortium/ITKPythonPackage

macOS and Linux are available. Windows packages will be available over the coming weeks.

The newer versions ITKBridgeNumPy use a NumPy array view, which does not do any copies during the conversion, and it is very fast.

Matt

Subject: [ITK] [ITK-users] Reconstruct non-transverse scanned MR images
Message-ID: <1493020478635.58701@sphic.org.cn>

?Hi all,


I have a set of DICOM MR images which is scanned in Coronal, not Transverse. As a result, when I reconstructed them to a 3D volume using ITK, its orientation seems to be not the same as the that of the Transverse scanned 3D volume, whose orientation is standard LPS. My questions are


(1) Should I reorientation the Coronal scanned 3D volume to standard LPS orientation?

(2) If need, should I use itk.OrientImageFilter to do that? Or use any other methods?

(3) If need use itk.OrientImageFilter, how to write "orienter->SetDesiredCoordinateOrientation(itk::SpatialOrientation::ITK_COORDINATE_ORIENTATION_LPS)" using Python?


Thanks in advance.



Regards,


Zhuangming Shen

Subject: [ITK] Level set with shape prior
In-Reply-To: <2123082733.4520850.1493044553702.JavaMail.zimbra@enst.fr>
Message-ID: <1266167915.4540440.1493045994809.JavaMail.zimbra@enst.fr>

Hello everyone,

I'm trying the level-set segmentation with shape guidance as described in the manual guide; the one based on the Leventon et al. paper "Statistical shape influence in geodesic active contours".
https://itk.org/Doxygen/html/Examples_2Segmentation_2GeodesicActiveContourShapePriorLevelSetImageFilter_8cxx-example.html

Unfortunately, I fail to make it works correctly : when I look at the shape prior during optimization, after the initialization with an usual centering helper, it "drifts" away of the feature image until it disappears, which obviously leads to weird segmentation behavior. I've tried to toy with parameters, setting high weight on gradient term (the only one that actually links the shape with the feature map) in MAP cost function, but nothing make it right. It feels like the shape prior make no sense. 
Also, the example include an optimization through the OnePlusOneEvolutionary, and I'm not sure random permutation is the best way to achieve good prior. In the paper they used a gradient ascent, so I tried the gradient descent, but alas the cost function does not support derivative-based optimization.

Have anyone applied this method successfully on their data ? Any hints welcomed 
Thanks in advance

Tim

Hello,

To the best of my knowledge and experience with the ITK pipeline, when the output of a filter ( H or R ) is used as multiple inputs with the ReleaseData, the data from the output ( H or R ) will be release after _each_ filter which use that output data. So the result is that the minimal amount of memory is consumed! But in a complex pipeline like yours filters will be executed multiple times for a single update.

Based on your comments you likely want to set only R and W to ReleaseData automatically. This ensures that all the inputs to M are cached and available. The trade off is that R will get execute twice. Alternatively, you could just manually release the output of R after execution.

HTH,
Brad

Dear Users,

I have trouble applying the concepts behind the release data flag, and memory management  of itk to a particular problem.

I?m developing a filter with, for part of it, it a rather complex mini pipeline.
H, R, RS, W, WS and M are itk filters.
The filter will be updated frequently, and I?m trying to make the update only update necessary parts, while keeping memory imprinting as low as possible.

Here is a schematic, simplified graph representing my filter :

    H
    | \
    v  \
    R   \    -> take as input a parameter P1 that do not change often
    |    \
   / \   /\
  v   v v  |
 RS    W   |
  |    |   |
  |    v   |
   \  WS   |
    \  |  /
     v v v
       M     -> takes parameters P2 that are often updated


I would like to be able to release the output data of the filter R and of the filter W, updating them only if the parameter P1 change (which would trigger update for the whole pipeline), while still being able to change P2 without having to recalculate R, W and RS.

I think it may be possible with the releaseData flag, don?t really understand where it should be putted, and if this will do what I need.

Thanks a lot for you help !
Yann

Hi Nirvedh,

For performance reasons, the iterators do not do bounds-checking.

Hi Fabio,

Yes, building Python extensions that depend on libraries like Cuda is muich
easier with CMake build system support in scikit-build.

I will follow up with an example of how to set up scikit-build for
ITK-based C++ code.

Thanks,
Matt

Hello,

You also need to graft the input and output so that updates and propagation of the mini-pipeline does not propagate beyond the mini-pipeline[1] [2].

Your approach sounds about right. But there are a lot of stumbling block with this approach and just a couple ways to do everything ?proper?. Also this goal of ?caching? the internal data, is not what is generally done in ITK. Most filters in ITK, prefer to release the data and keep memory usage to a minimum. It frequently turns out, that keeping a pipeline?s memory foot print small is important to fast execution and allows the processing to scale to larger data sets too.

The ?ReleaseData? flag does not cause the pipeline to be re-executed. You will have to examine the pipeline code and the time stamps of the relevant objects to determine the effect of ?manual? releasing the data, and how to best do it for your situation.

HTH,
Brad

Thanks for your answer Brad !

Just to confirm that I understood well:

To unsure that only the needed parts are actualized I call the global update, I need to:

  *
use the H, R, RS, W, WS, M filters as members
  *
set up their relationships in the filter constructor
  *
do the update at the M filter

Then I can call manually releaseData on the R and W filter after the call to M update().

And that should do the trick, and release data should not make the downstream filters RS and WS to update, right ?

Ok, after rereading what the software guide tells about that:

Filter execution occurs
when a) the filter is modified as a result of modifying an instance variable; b) the input to the filter
changes; c) the input data has been released
? ITK Software guide p. 200

So it seems like if I release the data of W or R, updating M will force WS and RS to update? Am I wrong ?

If I want the filter to have the expected behavior, Is it possible to trigger the update manually ?
I?m thinking of disconnecting RS and WS by using new smart pointers for R and W output, checking manually the modified state to conditionally call update when relevant.

Le 24/04/2017 ? 17:35, Lowekamp, Bradley (NIH/NLM/LHC) [C] a ?crit :


Hello,

To the best of my knowledge and experience with the ITK pipeline, when the output of a filter ( H or R ) is used as multiple inputs with the ReleaseData, the data from the output ( H or R ) will be release after _each_ filter which use that output data. So the result is that the minimal amount of memory is consumed! But in a complex pipeline like yours filters will be executed multiple times for a single update.

Based on your comments you likely want to set only R and W to ReleaseData automatically. This ensures that all the inputs to M are cached and available. The trade off is that R will get execute twice. Alternatively, you could just manually release the output of R after execution.

HTH,
Brad

Dear Users,

I have trouble applying the concepts behind the release data flag, and memory management  of itk to a particular problem.

I?m developing a filter with, for part of it, it a rather complex mini pipeline.
H, R, RS, W, WS and M are itk filters.
The filter will be updated frequently, and I?m trying to make the update only update necessary parts, while keeping memory imprinting as low as possible.

Here is a schematic, simplified graph representing my filter :

    H
    | \
    v  \
    R   \    -> take as input a parameter P1 that do not change often
    |    \
   / \   /\
  v   v v  |
 RS    W   |
  |    |   |
  |    v   |
   \  WS   |
    \  |  /
     v v v
       M     -> takes parameters P2 that are often updated


I would like to be able to release the output data of the filter R and of the filter W, updating them only if the parameter P1 change (which would trigger update for the whole pipeline), while still being able to change P2 without having to recalculate R, W and RS.

I think it may be possible with the releaseData flag, don?t really understand where it should be putted, and if this will do what I need.

Thanks a lot for you help !
Yann

Hello,

This parameter is used to assess if certain tests are run. If the value is
too low (I think under 8GB), a few tests will not be run. It will not have
any inpact on the ITK library and how it is compiled.
Hope this helps,

Hello Mathew,


It has not come up as a priority yet. Can you please add two feature requests to SimpleITK?s Github Issue tracker [1].

In general though ANTs is the go to interface for using the SyN algorithms [2] for most common applications.

Hallo,

I know it's possible to get a numpy array of an itk image with:

itk.PyBuffer[ImageType].GetArrayFromImage(Image)

Is it by any chance also possible to obtain a (flattended) numpy array of the physical coordinates of the image pixels too?

Thank you!

Hi!

You can generate an image of the physical locations of each pixel with the PhysicalPointImageSource filter:
https://itk.org/Doxygen/html/classitk_1_1PhysicalPointImageSource.html

Very recently added is the SetReferenceImage, which can be use to copy the meta data from one image to the parameters of this filter. If your version is not super recent then you can manually set the Size, Spacing, Origin, Direction and StartIndex.

After you generate the point image you should be able to convert to with the same method.

HTH,
Brad

Thank you for your reply.


1)     I have tried as a first step the following:

DRRPhy = itk.PhysicalPointImageSource[itk.Image[itk.Point[itk.F, Dimension], Dimension]].New()

But I get the error:

KeyError: "itkTemplate : No template (<class 'itkPointPython.itkPointF3'>, 3) for the itk::Image class"

So I guess I can?t generate an image with itk.Points as PixelType. Therefore I chose to use a VectorImage as ImageType in Input to the PhysicalPointImageSource.

sourceImage = itk.PhysicalPointImageSource[itk.VectorImage[itk.F, Dimension]].New()
sourceImage.SetSize(size)
sourceImage.SetSpacing(spacing)
sourceImage.SetOrigin(origin)
#DRRPhy.SetIndex(start) it does not work, how to set the start index?
DRRPhy.SetDirection(direction)


2)     However, using PyBuffer to get a numpy array form that does not work:

sourceImageArray = itk.PyBuffer[ImageType].GetArrayFromImage(sourceImage)

I get the error:

AttributeError: 'itkPhysicalPointImageSourceVIF3' object has no attribute 'GetLargestPossibleRegion'


Am I doing the right thing in point 1) ?
How could I solve point 2) ?

Thank you !

Fabio.

Hi!

You can generate an image of the physical locations of each pixel with the PhysicalPointImageSource filter:
https://itk.org/Doxygen/html/classitk_1_1PhysicalPointImageSource.html

Very recently added is the SetReferenceImage, which can be use to copy the meta data from one image to the parameters of this filter. If your version is not super recent then you can manually set the Size, Spacing, Origin, Direction and StartIndex.

After you generate the point image you should be able to convert to with the same method.

HTH,
Brad

Is it by any chance also possible to obtain a (flattended) numpy array of the physical coordinates of the image pixels too?

Thank you!

Subject: [ITK] [ITK-users] multiple itk filters in vtk pipeline issue
Message-ID: <MWHPR18MB0944D2F4B33C41E81C3B1967A9130@MWHPR18MB0944.namprd18.prod.outlook.com>

I am trying to apply image processing with itk through vtk pipeline. It seems no problems with single itk filter, but did not work well with multiple itk filters. The pseudo code is as following:


in constructor:


m_ItkImage = ItkImageType::New();

m_ItkImageFilter = ItkImageFilterType::New();


in image processing function:


m_ItkImage gets an image from vtk pipeline


m_ItkImageFilter->SetInput(m_ItkImage);

m_ItkImageFilter->Update();


m_ItkImageFilter->GetOutput() was sent back to the vtk pipeline


I debugged the m_ItkImage and m_ItkImageFilter->GetOutput(), and saw that m_ItkImage was updated but m_ItkImageFilter was not through the vtk pipeline.


How can I make m_ItkImageFilter->GetOutput() updated too through the vtk pipeline?


Thank you for your time.

	position	reporting
Message-ID: <CAJ0LxQ+LqyCHg41Xbwn4D=zaUtwWkdd-eEn1WCPvba-yTB1mtA@mail.gmail.com>

Hello,
I'm attempting to track the movement of images under registration using
various optimizers.  I have a CommandIterationUpdate observer set up to
write the optimizer positions to file, and when I use a Gradient Descent or
Powell optimizer I get a vector for the translation applied using
optimizer->GetCurrentPosition(), however if I use the LBFGSB optimizer I
get zero vectors all the way down (it returns the correct result though).
Is the functionality of GetCurrentPosition() different in the LBFGSB
optimizer than the others?

Hello Fabio,

I was able to use this filter in Python. Here is the commands I typed:
In [14]: ImageType=itk.Image[itk.Vector[itk.F,2],2]

In [15]: source=itk.PhysicalPointImageSource[ImageType].New()

In [16]: source.SetSize([5,5])

In [17]: source.SetOrigin([0,0])

In [18]: source.SetSpacing([.5,.5])

In [19]: source.Update()

In [20]: itk.GetArrayFromImage(source)
Out[20]:
itkndarray([[[ 0. ,  0. ],
        [ 0.5,  0. ],
        [ 1. ,  0. ],
        [ 1.5,  0. ],
        [ 2. ,  0. ]],

       [[ 0. ,  0.5],
        [ 0.5,  0.5],
        [ 1. ,  0.5],
        [ 1.5,  0.5],
        [ 2. ,  0.5]],

       [[ 0. ,  1. ],
        [ 0.5,  1. ],
        [ 1. ,  1. ],
        [ 1.5,  1. ],
        [ 2. ,  1. ]],

       [[ 0. ,  1.5],
        [ 0.5,  1.5],
        [ 1. ,  1.5],
        [ 1.5,  1.5],
        [ 2. ,  1.5]],

       [[ 0. ,  2. ],
        [ 0.5,  2. ],
        [ 1. ,  2. ],
        [ 1.5,  2. ],
        [ 2. ,  2. ]]], dtype=float32)

It also worked with VectorImages:

In [22]: ImageType=itk.VectorImage[itk.F,2]

In [23]: source=itk.PhysicalPointImageSource[ImageType].New()

In [24]: source.SetOrigin([0,0])

In [25]: source.SetSize([5,5])

In [26]: source.SetSpacing([.5,.5])

In [27]: source.Update()

In [28]: itk.GetArrayFromImage(source)


To answer your questions:
1) This filter is only wrapped over image of vectors and vector images. You
can have the list of types that are available in Python with
itk.PhysicalPointImageSource.GetTypes()
2) You may have a version of ITK Python for which VectorImage is not
wrapped for PyBuffer. You can try to update your ITK Python [1]

Hope this helps,
Francois

Hi Sean,

There are two filters in the ITKVTKGlue module (it has to be enabled
explicitly in your ITK build with the Module_ITKVTKGlue option) that are
used to glue together ITK and VTK pipelines. See these examples:


https://itk.org/ITKExamples/src/Bridge/VtkGlue/ConvertAnitkImageTovtkImageData/Documentation.html


https://itk.org/ITKExamples/src/Bridge/VtkGlue/ConvertvtkImageDataToAnitkImage/Documentation.html

Hope this helps,

Hi Andrew,

different optimizers have different behavior (e.g. small steps vs big
steps), but even the programming interface is not uniform. Some functions
are called differently e.g. maximumSteps vs iterationCount etc. You should
look at the respective examples for each optimizer which you plan to use to
see how iteration tracking is set up.

D?enan Zuki?, PhD, Senior R&D Engineer, Kitware (Carrboro, N.C.)

Subject: [ITK] [ITK-users] [itk] Unhandled exception when using Mean Squares
	and	Powell Optimizer
Message-ID: <CAJ0LxQLokh8-7bGsDtM3zgPAEbnUnHAO7X1VBxDXGHucnWRoKQ@mail.gmail.com>

Hello,
I'm getting an exception saying too many samples are outside the moving
image buffer when I use the MeanSquaresImageToImageMetric with the
PowellOptimizer that doesn't occur when I
use NormalizedCorrelationImageToImageMetric
or MattesMutualInformationImageToImageMetric.  I thought it might be
because the optimizer is seeking to maximize the metric so I tried calling
MaximizeOff on it but got the same exception.  Any ideas would be
appreciated.

Hi Andrew,

if this is happening on the first iteration, your initial parameters do not
overlap your images well. If this is happening in some later iteration, the
other optimizer might be veering of course during optimization, pushing
your images apart and ultimately causing the error. From experience, the
initial parameters are almost always to blame.

Regards,
D?enan

Hi Swetha,

combine image->TransformPhysicalPointToIndex()
<https://itk.org/Doxygen/html/classitk_1_1ImageBase.html#af4a7c9c3787e9fdafbaaade2e02efa25>
to
see if the point is in the image and image->GetPixel()
<https://itk.org/Doxygen/html/classitk_1_1Image.html#ad424c945604f339130b4ffe81b99738e>
to
check whether the value is greater than zero.

Regards,
