I am at version skimage 0.8.2, Python 2.7.2+, os: Linux Mint 12 Lisa.

Could you try with the latest version from GitHub? It might have been a bug in 0.8.2.

Just to expand on Stefan's reply: the old implementation (0.8) searched for any part of the circle in the image, so the center could as much as "r" outside the image. You can convert the 0.8 result to the 0.9 result with hough_result = hough_result[r:-r, r:-r] Best, Tony
