Hi all,<br><br> I have a question about conversion of deformation field from low resolution to high in Examples/DeformableRegistration6. I do not understand<br>why we need both ResampleImageFilter and BSplineDecompositionImageFilter. I think we only need to up sample the deformation field (per dimension) <br>
using ResampleImageFilter with BSplineResampleImageFunction. <br><br> Then, why is the output of ResampleImageFilter fed into BSplineDecompositionImageFilter and then put into the parameters? What does BSplineDecompositionImageFilter do? <br>
I cannot get this from the document of BSplineDecompositionImageFilter.<br><br>Thanks,<br>Mengda <br>
