For a motion-estimation algorithm, we’d like to be able to calculate the Jacboian of b-spline coefficients. Alternatively (and less computationally expensive), we’d like to be able to apply this Jacboian onto a pre-existing transformation.
We would like to do this in ITK or VTK, whichever is easier. Matching VTK post is here.
Could anyone point us to the relevant classes/methods (dare I say examples) for this?
