[Insight-users] ResampleFilter for 3D image

Tue May 18 12:54:14 EDT 2010

Thanks.

I tryed to do what you said me but now I've a new problem.... I wanted
to preserv the original x and y dimension of my image and only reslice
it; I've to use  this resample filter with different images and so I
want a more general possible code.... so I try to do this:

#include <itkImageIORegion.h>   

[...]

InputImageType::Pointer image = reader->GetOutput();

SizeType imageSize = image->GetLargestPossibleRegion().GetSize();

but when I've this error:

terminate called after throwing an instance of 'itk::ExceptionObject'

  what():  /usr/local/include/InsightToolkit/IO/itkImageFileWriter.txx:271:

itk::ERROR: ImageFileWriter(0x8956220): Largest possible region does
not fully contain requested paste IO regionPaste IO region:
ImageIORegion (0xbfcc9ba8)

  Dimension: 3

  Index: 0 0 0 

  Size: 0 0 50 

Largest possible region: ImageRegion (0xbfcc9c04)

  Dimension: 3

  Index: [0, 0, 0]

  Size: [0, 0, 50]

Aborted

Could someone help me to solve this problem?

Thanks

Daniela,
You commented out these lines
  //size[0] = 300;  // number of pixels along X  //size[1] = 300;  // number of pixels along Y
As a result, the values in size[0] and size[1] aren't initialized. In the error, you can see that these dimensions have the values 3216878376 and 138384173, which is surely much larger than the dimensions of your image. Please try uncommenting these lines and setting the image dimensions appropriately and report back what happens.

Thanks,
Cory

Hi everyone
I'm new in itk....so, sorry for my (maybe stupid) questions.

I have to resample a 3D US image (it is a 97 frames image and I want to reduce its frame-number to 50).
I tried to adapt ResampleImageFilter (Examples/Filtering/ResampleImageFilter.cxx.) for 3D image. I wanted to run it to see how that filter works but  I've this error:

I think that my code is wrong but I don't find my (propably stupid) error....

I add my wrong code to this mail...

Thanks all
Daniela
