Using the built in circle detection algorithm, I have trouble to find the biggest circle.
For example:
HoughCircles(src_gray, circles, CV_HOUGH_GRADIENT, 1, src_gray.rows / 8, 200, 20, 10, 50);



I only draw the best detection, but it seem to be the average of the actually detected circles.
How can I detect the biggest one?
