An assortment of diffusion based image filtering methods:
1. Linear Diffusion Filtering using heat equations - solved using both implicit and explicit Euler methods.
2. Edge Enhancing Linear Anisotropic Diffusion Filtering.
3. Edge Enhancing Non-linear Anisotropic Diffusion Filtering.
Data files for test images are included. Each file is a script that implements one of the above methods. Read the comments for details.

What about implementing the following method:
can i use 22.214.171.124(R14)...??
@jichao, Image denoising
what kind of applications it may apply to ?
hi Ritwik, thanks for your reply. Looking for the new version :)
Hi Jane, it seemed like a typo in the comment. I fixed it and the updated files should be available soon. Thanks for pointing it out.
in your "non-aniso.m", you said "non-aniso.m demonstrates Edge-preserving non-linear isotropic filtering for denoising".
why "non-aniso.m" demonstrates non-linear isotropic filtering?
"non-aniso.m", why it demonstrates Edge-preserving non-linear isotropic filtering"?
I think so, please try it and if you run into some trouble, let me know and I can suggest some work around.
can I use matlab 7.8 (R2009)?
