[Vv] clitkResampleImage

[Benoît Presles]

Dear vv users,

When I use clitkResampleImage to resample the image result.nii like the 
image SUVImg.nii (clitkResampleImage -i result.nii -l SUVImg.nii -o 
resampleCLITK.nii), the origin of the resampleCLITK image is not the 
same as the SUVImg image 
(https://cloud.u-bourgogne.fr/index.php/s/LMzrtE1HvegjIaY).
I did not expect this behaviour especially with the "like option".

It is because line 231 in clitkResampleImageWithOptionsFilter.txx, you 
modify the output origin:
// Compute origin based on image corner
   for(unsigned int i=0; i<OutputImageType::ImageDimension; i++) {
     m_OutputOrigin[i] -= 0.5 * input->GetSpacing()[i];
     m_OutputOrigin[i] += 0.5 * m_OutputSpacing[i];
   }

Is there any reason?


Thanks for your help,
Cheers,
Ben
