i have a grey image , now i want to get the GLCM Contrast image , GLCM Homogeneity image like behind image example showing in the next page: http://hi.csdn.net/attachment/201111/25/4133400_1322185742CCIR.jpg who can explain it to me ?

That link shows up as "access forbidden" when I try.

Works for me. Maybe it's your corporate policy. I know there are some domains I can't get from work.

From the Image Processing Toolbox help:
Description
glcm = graycomatrix(I) creates a gray-level co-occurrence matrix (GLCM) from image I. graycomatrix creates the GLCM by calculating how often a pixel with gray-level (grayscale intensity) value i occurs horizontally adjacent to a pixel with the value j. (You can specify other pixel spatial relationships using the 'Offsets' parameter -- see Parameters.) Each element (i,j) in glcm specifies the number of times that the pixel with value i occurred horizontally adjacent to a pixel with value j.

It basically tells you how uniform an image is by telling you how varied are the gray levels next to a pixel.
