I have a hough-circles implementation (which I've been meaning to contribute). Unfortunately, my implementation does a pretty poor job when there's a large range of circle size and when the circles are close/overlapping.
I'm not sure this is your implementation's fault--aren't the parameters just overly sensitive in general? I searched for a different parametrization, and found this paper on the arxiv: http://arxiv.org/abs/cs/0301001v1 Have you ever seen the Hough transform implemented using this formulation? (A(x^2 + y^2) + B(x) + C(y) + D). Maybe we're on to something :) I'd love to be able to solve Siggi's problem--this is exactly the kinds of things our toolbox should be able to address. Stéfan
