Most of the natural textures are non-homogenous and stochastic by nature. In many cases these textures are also directional. In this paper we present a method for the retrieval of the non-homogenous directional textures. This method is directional histogram and it represents the directional distribution of the texture. The histogram can be formed using either directional filtering method or Hough transform. We test the retrieval ability of our methods using rock texture images. The directional histogram method gives clearly better retrieval results than Gabor features and co-occurrence matrix.
