I have added a vessel enhancement filter to Matlab function itk_imfilter().
http://code.google.com/p/gerardus/source/browse/trunk/matlab/ItkToolbox/ItkImFilter.cpp
It's an anisotropic diffusion filter. The implementation is from
Enquobahrie A., Ibanez L., Bullitt E., Aylward S. "Vessel Enhancing
Diffusion Filter"

of a paper by
Manniesing R, Viergever MA, Niessen WJ, "Vessel enhancing diffusion: A
scale space representation of vessel structures", Medical Image
Analysis, 10(6):815-825
Best regards,
Ramon.
