Texture analysis using Renyi's generalized entropies
Simona E. Grigorescu, J.M.F. Petkov · 2004
In this paper, we propose a texture analysis method based on Renyi's generalized entropies. The method aims at identifying texels in regular textures by searching for the smallest window through which the minimum number of different visual patterns is observed when moving the window over a given texture. The results show that any of Renyi's entropies can be used for texel identification. However, the second order entropy, due to its robust estimation, is the most reliable. The main advantages of the proposed method are its robustness and its flexibility. We illustrate die usefulness and the effectiveness of the method in a texture synthesis application.
