[ITK-users] [ITK] How to Calculate Hessian Matrix from Gradient Image?

[Jakob Weiss]

Thank you a lot Matheus, this has been very helpful!

As to the question of using the Jacobian: Since the Hessian s the same as
the Jacobian of the Gradient, this just another equal formulation of the
same problem. I could not find any filter for computing the Jacobian on a
vector volume either, so not really a solution. For example [1] applies a
scheme to make these matrices symmetric.

Cheers,
J
