Title: Extraction of color image texture feature based on gray-level co-occurrence matrix
Abstract: Texture plays a very important role in image retrieval and classification,and texture feature extraction has been a research hotspot. Most present existing texture extraction algorithms can be only used to calculate texture features of gray image. Texture extraction algorithm for color image is very few. Referring to the analytical method of gray level co- occurrence matrix( GLCM),the authors analyzed the influence law of parameters( direction, distance,grayscale,window size) on GLCM texture features of color image. A color image texture feature extraction method( color GLCM,CGLCM) based on GLCM was realized. Through analyzing the influence law of these parameters on four texture features( ASM( angular second moment),Entropy,Contrast,Correlation),a proper parameter value range was given and the CGLCM method was optimized. The results of comparing CGLCM method with GLCM method show that the four texture features calculated with CGLCM method have better robustness and identification capability. These results can provide reference for image retrieval and classification based on texture information.
