If you are attempting to retrieve the matrix of data corresponding to an image object that is being displayed, then get() the CData property of the image object handle.

Yeah, there's lots of them in the Image Processing Toolbox. Why don't you post your image somewhere (your favorite file sharing web site) and ask something specific about that specific image?
