[Insight-users] Inverse BSplineDeformableTransform

[Vincent A. Magnotta]

Lars,

The GetInverse Method is not implemented for the BSpline transform.
There are two solutions for generating the inverse. The first is to get
the deformation field from the transform and then invert the deformation
field using the InverseDeformationFieldImageFilter. Another solution is
to generate a regular sampling of points in the fixed image space and
map these back to the moving image space using the BSpline transform.
These points can then be used to create a Thin plate spline transform
that is an approximation to the inverse of the BSpline transform.
