Hough Transform for circle detection

An optimized Hough transform for circle detection.

You are now following this Submission

This Hough transform is highly optimized. It uses the midpoint circle algorithm to draw the circles in voting space quickly and without gaps. It also includes an option for searching only part of the image to increase speed if a rough estimate of the circle locations is known.
