Forward and backward anisotropic diffusion filtering for color image enhancement
Bogdan Smołka, M. Szczepański · 2003
A novel approach to the problem of edge preserving smoothing, which allows an image to be broken into a set of homogeneous regions, is proposed and evaluated. The new algorithm is based on combined forward and backward anisotropic diffusion with an incorporated time dependent cooling process. This method is able to remove image noise efficiently while preserving and enhancing image edges.
