Re: Circle Detection

Hello:    

I don't know if this information helps you in something, but it's all
i can tell you in a simple mail.    
The "Hough Transform" algorithm used in the OpenCV library is a
improvement of the original algorithm. This improvement uses the
information of the gradient vector to reduce the computacional cost.  

I know that this algorithm is based in:   
Gerig G, Klein F (1986)   
"Fast contour identification through efficient hough transform and
simplified interpretation strategy".   
Proceedings 8th Int. Conf. on Pattern Recognition, Paris, France
498?500    
Sorry, I can't tell you any more, because I don't Know any more.
