Widespread in nature Texture, texture is the most essential properties of the surface. Texture analysis has been a hotspot in research. As the primary task of texture analysis, texture feature extraction is the focus of study. This paper puts forward a texture features extraction method for the five kinds of wood grain with the gray level co-occurrence matrix. The MATLAB simulation results show that the gray level co-occurrence matrix generated by the four texture features can effectively describe the texture characteristics of wood with good differentiation
