Aya, what features are you concerned about? The (x,y) locations of all the edge pixels? Something else? Please start your own question and attach your image. In the meantime, I've attached some of my demos for you.

Well, first you read in your image with imread(), and then you apply functions such as bwlabel, regionprops, imshow, etc. See demo in my File Exchange if you want tutorials and demo code. http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
