There exists a large number of techniques for content-aware smoothing.Despite its simplicity, the Perona-Malik Anisotropic Diffusion method is among the most employed ones.In this work we study this method in detail and propose a generalization of its diffusion scheme using restricted dissimilarity functions to measure the intensity differences between neighbouring pixels.This generalization permits a better adaptation of the diffusion process to the characteristics of the images.
