Please if someone has done this, please can you tell me,
"how to construct the contrast pairs from the image using the eight neighbors of each pixel"
and
"How to classify the contrast pairs of each image into two classes: edge and smooth" using the below method.... The edge contrast pair is found in the boundaries and texture regions, while the smooth contrast pair is found in the flat regions. To classify the pairs, the intensity difference between the pair’s intensities is taken. If it exceeds some defined threshold ε ( ε = 10 intensity levels), then it is considered an edge contrast pair; otherwise it is considered a smooth contrast pair.

Sounds like you could use either rangefilt() or graycomatrix(). Experiment around with both.

They are functions in the Image Processing Toolbox so there should be documentation and examples in the help.
