Hi Amit, It is about the Edge Detection, go through Gonzalez book Chapter 10 (Image Segmentation), if you have any specific question on a certain line or term, you can post here.
Good Wishes

Thank you so much. I will look at the book and get back to you if I run into any trouble.
Yes, that's the question. There are simply too many MATLAB files attached with the question. I don't know where should I start.
Here is the link to the matlab files.

The file size is 9 MB so I couldn't upload here.

Can you use imgradientxy() in the Image Processing Toolbox?

i tired it on some images. it gives better result than the edge function. I hope i can use it for assignment. i used Prewitt gradient operator which is a gradient based edge detector.
what do you think? would it be all right to use on the assignment?
