This collection of M-files takes as input a close-up image of the human iris and returns as output the original image overlaid with circles corresponding to the pupil and iris boundaries. In addition, it returns the centre and radius coordinates of both boundaries in the variables ci and cp.Notes on the use of the function(s) are included in the .txt files. All the functions have to be on the search path for the code to work.
Unfortunately, I wrote this a long time ago (2007) and no longer have the time to support it. You are of course free to extend and reuse this if it helps you.
