How to implement Hough Circle in Java

Question

i want to find a circular object(Iris of eye, i have used Haar Cascase with viola Jones algorithm). so i found that hough circle would be the correct way to do it. can anybody explain me how to implement Hough circle in Java or any other easy implementation to find iris with Java.

Thanks,

Answer 1

Duda and Hart (1971) has a pretty clear explanation of the Hough transform and a worked example. It's not difficult to produce an implementation directly from that paper, so it's a good place for you to start.

ImageJ provides a Hough Circle plugin. I've been playing around with it several times in the past. You could take a look at the source code if you want or need to modify it.
