[Insight-users] computing velocity field curl

[Marta Peroni]

Dear All,
I'm trying to compute the curl (rotor) of a velocity field obtained with
Dyppheomorphic Demons (Vercauteren implentation in the insight journal).
I saw some pieces of code for computing derivatives (e.g. GaussianRecursive,
CentralImageDifference etc), but for curl you need mixed derivatives...
Does any of you happen to know an approach to compute the curl?
Any hint will be appreciated!
thanks a lot!
marta
