∎ The GLCM is calculates how often a pixel. The GLCM characterizes texture based on the number of pixel pairs with specific intensity values arranged in specific spatial relationships. Another statistical method that considers the spatial relationship of pixels is the gray-level co-occurrence matrix (GLCM), also known as the gray-level spatial. The Gray Level Co-occurrence Matrix1 (GLCM) and associated texture feature calculations are image analysis techniques. The GLCM functions characterize the texture of an image by calculating how often pairs of pixel with specific values and in a specified spatial relationship occur.
