[Insight-users] DeformableRegsitration1

[Jayme Kosior]

Hi Josiane,

If you just want the output of DeformableRegistration1 to be of type 
unsigned short (or any other type for that matter), then you could just 
add the following lines:

   typedef itk::Image<unsigned short, 2>                            
Image2DType;
   itk::ImageFileWriter<Image2DType>::Pointer warpWriter;
   warpWriter =  itk::ImageFileWriter<Image2DType>::New();
   warpWriter->SetFileName((X->GetResultsFileName()).c_str());
   std::cout << "Writing to file: " << X->GetResultsFileName().c_str() 
<< std::endl;
   warpWriter->SetInput(X->GetWarpedImage() );
   warpWriter->Write();

This way you don't have to modify the actual filter.  In your case, you 
will need to setup the FEMRegistrationFilter to have unsigned short 
input/output images.

The key idea is that you can obtain the output using 
FEMRegistrationFilterObject->GetWarpedImage() and set this to the input 
of the writer..

Regards,

Jayme Kosior
