[Insight-users] Re : 3D Fourier Descriptors in itk? please help!

[Luis Ibanez]

Hi Marion,


              Your email is contradictory.


First you say that you want:

   "Fourier descriptors of a volume (surface points)"

but then you say that you want:

   "I'm looking for 3D fourier descriptors acting on voxels."


Please clarify,



Also,
Would you consider using Spherical Harmonics
as approximation to the Surface (Mesh) ?



   Thanks


     Luis
