[Insight-users] Generating a velocity field from a deformation/displacement field

Hello everyone,

Is there an easy way in ITK to generate a velocity field from a
deformation field? I have a displacement field where each voxel
contains a displacement vector (transformed position - initial
position). What would be an easy way to estimate the velocity field? I
am guessing the velocity field would just be the first derivative of
this deformation field. Is that correct?

Cheers,

Anja
