comment Identify circles with hough circle
Also, given the size of the circles and the fact that some of them will be skewed, the Hough transform is probably not a very good choice. You would probably do better to look for the specific colors of the markers.

Try looking at the Canny edge map with the same parameters, and see if the circles are even visible there. Once you have the parameters to Canny working well enough, the Hough transform will be more likely to work.
