Texture Suppression Preserving Edges by Anisotropic Diffusion

This article is devoted to a new method for removing texture in images using a smoothing rotating filter is presented. The novelty of this approach resides in the association of a descriptor able to classify a pixel as a texture pixel, a homogenous region pixel or an edge pixel with an anisotropic edge detector which defines two directions used in anisotropic diffusion. This anisotropic diffusion controls accurately the diffusion near edge and corner points and diffuses isotropically inside textured regions. Our results applied on a real image and a comparison with anisotropic diffusion methods show that our model is able to remove efficiently the texture of regions while preserving edges.
