Texture feature extraction using gray level gradient based co-occurence matrices

The gray level co-occurrence matrix (GLCM) has long been a powerful tool for texture analysis. In this research, the gray level gradient co-occurrence matrix (GLGCM) is developed to capture the second order statistics of gray level gradients. Subsequently, a set of texture features is extracted from the GLGCM. Experimental results confirm the effectiveness of this set of features are given in this paper.
