DWHT: A fast multi-scale/multi-directional texture feature extraction scheme

Abstract

A new Walsh/Hadamard-based texture feature extraction method would be proposed in this paper. This method, called Directional Walsh/Hadamard Transform or DWHT, tries to insert the basic advantages of multi-scale/ multi-directional texture analysis into a fast modified Walsh/Hadamard transform. A comparative test amongst several texture feature extraction algorithms applied on a database of VisTex. textures, illustrates the efficiency of the proposed method in both classification accuracy and the computational costs.
