[Insight-users] How do you get a MATLAB variable to ITK?

[Akiko Campbell]

I normally write the MATLAB variable into a raw file and read it into
ITK with the MHD header.

For example,

***MATLAB***
Name    Size          Bytes     Class
v1      256x256x130   68157440  double array

fid=fopne('v1.raw','wl')
fwrite(fid,v1,'double');

***v1.mhd***
NDims = 3
DimSize = 256 256 130
ElementType = MET_DOUBLE
ElementSpacing = 1 1 1
ElementByteOrderMSB = False
ElementDataFile = v1.raw
 
***ITK***
typedef itk::Image< itk::Vector<double,3>, 3 > VectorImageType;
typedef itk::ImageFileReader< VectorImageType > VectorReaderType;
VectorReaderType::Pointer reader = VectorReaderType::New();
reader ->SetFileName("v1.mhd");
reader ->Update();


I don't read the variable back from ITK to MATLAB but I think something
similar to the above might work.  I hope this helps.

Hello everyone,

I have a question concerning Matlab and ITK.  How can one get a variable
(i.e. image) from Matlab into ITk and then from ITK back into Matlab. 
Any helpful advice on this would be greatly appreciated.

Thanks : )
