I used glcm to extract the statistical features from the gray scale images. it gave me information 256*256 scale..But I'm confused ,I have seen in same places a window size

Yes, suppose you extract the statistical feature suppose (mean) of an image having size 256*256, If yousliding the window pixel by pixel, then definitely you will get the feature matrix having the same size as its original image.

But if the sliding window is non-repeating case for all pixels, then the resultant statistical feature matrix will be original_size/window_size (considering padding or exact divisible)

Suppose original matrix is 30x30, and window size is 3x3, then resultant feature matrix will have size 10x10

Hope it helps to clear your doubt.
