This is a very vague question and it does not stress the fact enough that this is your project. I we explain, how you have to implement this in Matlab, it would be our project.
I suggest to try to find out as much as possible by your own and use the forum to ask specific Matlab related questions, which can be answered preferrably in 4 sentences or 10 lines of code. Image Analyst will post 200 lines of code also, but even he needs a more detailed questions.
I personally detest to implement something in Matlab, which will loose a competition with a 1 year old child. It is like the construction of a machine which stirs my coffee - from a global point of view it does not solve anything, which could not be done with a smaller amount of time and energy. There are so many really useful jobs, which are waiting for a programmer. But this is only my personal view.
