View Full Version : Edge detection algorithm

Hi all.
I need your help in implementing a hough trasform to find pupil and iris. I need to implement iris recognition algorithm for my final year project. It is part of project. So anyhow I need to find methology to edge detection algorithm. Help to do this. Time is going fast. (source code also required [canny or sobel] )

I tried to look up the hough transform. It seems like there are many parts of the algorithm that are outside my area of expertise, however, you asked to help implement the transform. Can you provide pseudo-code and a programming language and maybe someone can help outline some of the pieces?

Or are you just asking for help implementing canny or sobel edge detection?
In that case, try looking at Edge Detection Tutorial (http://www.pages.drexel.edu/~weg22/edge.html) and Canny Edge Detection Tutorial (http://www.pages.drexel.edu/~weg22/can_tut.html)
It seems that those two pages are a tutorial on how to implement canny and sobel algorithms.

If you have any specific implementation questions please ask. I'm sure you realize that we are not here to do your work for you, especially when it comes to a final year project.

First of all I'll thanks for you.

These two articals are enough to start my part. I know final year projects are very complex and do lot of things to start. Any way I found good path from you. Thanks.

Hi ,
I need a m-file in matlab for Iris Localization in image.

Thanks a lot.
