Gray Matrix Method for Texture Retrieval: History and Applications

The gray matrix method of texture retrieval was first proposed in English literature by Jiebo Luo and Jie Yu in their paper 'Gray Matrix: A Novel Method for Texture Classification and Retrieval' published in the Proceedings of the 1999 IEEE Computer Society Conference on Computer Vision and Pattern Recognition. The method is based on the idea of representing texture images as gray-level co-occurrence matrices (GLCMs) and using a distance metric to compare these matrices for retrieval purposes. The gray matrix method has since been widely used in the field of computer vision for texture analysis and retrieval.
