Abstract: Texture classification is one of the most studied and challenging problems in computer vision. A key requirement of successful texture classification algorithms is their ability to quantify the complex nature and diversity of real world textures. Recent developments in automatic texture classification have demonstrated the effectiveness of representing texture elements as cluster centers of convolution responses of a filter bank. These representation of texture elements are called textons. Such methods rely primarily on similarity measurements of frequency histograms of vector quantized versions of the target texture. A main problem with these approaches is that pure frequency histograms fail to account for important spatial interaction between textons. Spatial interaction is key to classification when analyzing textures with similar texture element frequency but differ in the way the texture elements are distributed across the image. In this paper, we propose the use of co-occurrenc e statistics to account for the spatial interaction among texture elements. This is accomplished by calculating spatial co-occurrence statistics on the maps of textons generated by the vector quantization procedure. We demonstrate the effectiveness of our method on images from the Brodatz album as well as natural textures from a tropical pollen database. We also present a comparison with a state-of-the-art method for texture classification. Finally, our experiments show that the use of spatial statistics help improve the classification rates for certain textures that present sparse and statistically non-stationary texture elements such as pollen grain textures.
