one question is that I can't duplicate the fig 3 in
G. Grieg, O. Kubler, R. Kikinis, and F. A. Jolesz, Nonlinear Anisotropic Filtering of MRI Data, IEEE Transactions on Medical Imaging, 11(2):221-232, June 1992".
the fig 3 show iterative edge sharpening, but my simulation gives me reverse result... can anyone give me a sample code for results similar to fig 3?
thanx fr the code it is easy to understand bt in the perona-malik paper divergence is taken for the diffusion process nd in dis code diff-image is calculated in some different way. can u plz explain m dis?
