[Insight-users] Convert point correspondences to dense deformation field?

[Zachary Pincus]

Hello folks,

I'm wondering if there are any methods in ITK, or methods easily  
implementable with tools from ITK, for converting a (very) sparse  
deformation field (e.g. a set of point correspondences) to a smooth,  
dense field?

Perhaps a good approach would be to follow that of the  
InverseDeformationFieldImageFilter
( http://www.itk.org/Doxygen/html/ 
classitk_1_1InverseDeformationFieldImageFilter.html ) which creates a  
kernel-based spline from the known deformation vectors, then gets a  
dense field from the spline?

Are there any other approaches, or does anyone have any tips for  
pursuing the above approach?

Thanks,
