A Directional Filtering Approach to Texture Discrimination

Image decomposition in directional components is a powerful tool for analyzing edge informationl. Its application to the representation of textures is justified by the fact that directional edge information seems to play an important role in texture discrimination. The properties of directional filtering are used for selecting the features to describe textures. The results obtained from the classification of textures on the basis of these features seem to encourage this kind of approach. They prove that local observation of features to which the visual system is sensitive leads to correct classification.
