spot detection on human iris

how can i detect spots on human iris image before training using back propagation network?

I guess you can use image processing. Will that work for you?

thanks for your reply, can you please be specific with the part i should focus on? thanks

You weren't specific (e.g. no image or code posted), so I just followed your lead.

You first need to get your algorithm. Go here: VisionBib and look at this section:

21.5.3 Biometrics, Iris Recognition Systems

Of the 513 articles that have iris in the title, no, I don't know which one is best, or which ones have MATLAB code that the authors are willing to send you or sell you. I've never done an iris analysis project myself. But there are several steps (1) locating the iris, (2) identifying unique identifying features in it, and (3) comparing that feature vector against others in your database. I presume you already know what you're going to do in step 2 because you mentioned some kind of "back propagation network" that you're going to send it into. I'm not a neural network user either. Once you have the features via image analysis, then list those features (the variables and the form they take), and ask a question more targeted to neural networks if you want people to help you with that part. Good luck.
