Hi All,

Am I right that there is not currently an implementation of

a) a Gaussian derivative operator that can compute 2nd degree symmetric and
asymmetric derivatives along a compete 3D neighborhood

b) and consequently no easy way to compute a 3D Hessian matrix for each
voxel

c) and also no solver for eigenvalues of symmetric 3x3 matrices?
