[Insight-developers] Ctest --compare fails on vector images

[Luis Ibanez]

Hi Danielle,

Thanks for pointing this out.

Yeap, that's the case.

The --compare option is implemented in

    ITK/Code/Common/itkMainTest.h

The implementation of RegressionTestImage() in

    ITK/Code/Common/itkMainTest.h

is not appropriate for VectorImages.
It uses by default an image of type

typedef itk::Image< double, ITK_TEST_DIMENSION_MAX > ImageType;


with #define ITK_TEST_DIMENSION_MAX 6


When reading an image of multiple components,
only the first component will be seen in this filter.

I have now enter this as a feature request in:
http://public.kitware.com/Bug/view.php?id=11489


The implementation will require to discover at
run time whether the input image is a vector image,
and... to define a metric for comparing vector images.


Would you be interested in giving it a shot at
implementing a fix ?


     Thanks


          Luis
