[ITK] Python wrapper for first order ITKTextureFeatures

[yannick.suter at istb.unibe.ch]

Dear all,

I would like to use the the first order texture features of ITKTextureFeatures (https://github.com/InsightSoftwareConsortium/ITKTextureFeatures) in Python. Thanks to J.Vimort et al. for the great work!
Since the coocurrence and run length features are already wrapped, I tried to take these as an example and wrap it myself (I'm very new to this).

I would appreciate any help to point me into the right direction.

That's what I've tried:
- Created a .wrap file "itkFirstOrderTextureFeaturesImageFilter.wrap" and put it in the "/Modules/External/ITKTextureFeatures/wrapping" directory (see below)
- Added "itkFirstOrderTextureFeaturesImageFilter" to the CMakeLists.txt in the "/Modules/External/ITKTextureFeatures/wrapping" directory, now looking like this:

itk_wrap_module(TextureFeatures)

set(WRAPPER_SUBMODULE_ORDER
   itkCoocurrenceTextureFeaturesImageFilter
   itkRunLengthTextureFeaturesImageFilter
   itkFirstOrderTextureFeaturesImageFilter)

itk_auto_load_submodules()
itk_end_wrap_module()

This gives me the folowwing error for every datatype I set to wrap:
>> /home/yannick/Projects/PhD/ITK/ITK/bin/Wrapping/itkFirstOrderTextureFeaturesImageFilter.cxx:79:18: error: too few template arguments for class template 'FirstOrderTextureFeaturesImageFilter'
>>    typedef itk::FirstOrderTextureFeaturesImageFilter< itk::Image< signed short,2 >, itk::Image<itk::Vector<float,8>,2> > itkFirstOrderTextureFeaturesImageFilterISS2IVF82;
                 ^
>>/home/yannick/Projects/PhD/ITK/ITK/Modules/External/ITKTextureFeatures/include/itkFirstOrderTextureFeaturesImageFilter.h:52:27: note: template is declared here
>>class ITK_TEMPLATE_EXPORT FirstOrderTextureFeaturesImageFilter:

Since the it's working if I use it in C++, I don't see where template arguments are missing.

Best and thank you,

Yannick

That's my .wrap-file:
