"WebJan 18, 2024 · So, my understanding is: Create moving window of size 5x5. move this window over your input image. for each window position (x,y), calculate a feature (e.g. contrast), and write the value for this feature into the "contrast" image at position (x,y). This way, you extract "local" features, i.e. the GLCM is only done over local area of size 5x5. " - Glcm image processing book
