In matlab we have a command called improfile. I want to use it to plot a graph of comparison between shadow and non shadow areas in an gray image... My input image is gray image with shadows on some regions... The Improfile should contain 2 graphs one representing shadow pixles and other non shadow pixles... any help on this...

Just call it and get the profile. Then threshold into dark and light areas and graph them. Did you have some trouble with the code?

See attached demo for improfile.

There are more sophisticated shadow identification methods than simple thresholding. Let me know if you need references.
