Jacobian of B-spline coefficients

[rijobro (Richard Brown)]

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?

A few pointers:

• itk::BSplineTransform ComputeJacobianFromBSplineWeightsWithRespectToPosition
• itk::BSplineTransform ComputeJacobianWithRespectToParameters
• itk::TransformToDisplacementFieldFilter
• itk::DisplacementFieldJacobianDeterminantFilter

Hi Matt,
Great thanks for the pointers!
