= Diffusion image processing

Diffusion filtering evolves an observed <image signal> using a <diffusion equation>. The <heat equation> gives Gaussian <image smoothing>, while gradient-dependent or tensor-dependent diffusion can reduce transport across <image edges>. A <image smoothing> scale, stopping rule and appropriate boundary conditions are part of the filter.
