Ramana,

Have you looked at the InvertDisplacementFieldImageFilter?
https://itk.org/SimpleITKDoxygen/html/classitk_1_1simple_1_1InvertDisplacementFieldImageFilter.html

It was my understanding that the above is the preferred inversion algorithm. 

I actually have the wrapping code for  FixedPointInverseDisplacementFieldImageFilter sitting around. I can make this available if needed. However, documentation improvements need to be made to these classes to clarify the differences.

Please add a feature request on Github if this is something you really need:

Thanks,
Brad

    Hi Ziv,
    
    Thanks very much, that's exactly what I needed.
    
    I needed the matrix for some code I'm writing to invert a displacement
    field. The fixed-point deformation field inversion isn't included in the
    SimpleITK python libraries, so I'm going about implementing it myself.
    
    Anyway, thanks very much for the help again!
