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.
