WebbThe Hough transform in its simplest form is a method to detect straight lines [1]. In the following example, we construct an image with a line intersection. We then use the … WebbThis will give you the radius of the circle with the same area as the hole, and corresponds to one method to obtain a best fit circle. A different way of obtaining a best fit circle is to take the contour of the hole (as returned in cnts by cv.findContours in nethancy's answer), finding its centroid, and then computing the mean distance of each vertex to the centroid.

"WebbIn order to detect the circles, or any other geometric shape, we first need to detect the edges of the objects present in the image. The edges in an image are the points for which there is a sharp change of color. For instance, the edge of a red ball on a white background is a circle. In order to identify the edges of an image, a common ... " - Skimage hough circle

In the following example, the Hough transform is used to detect coin positions and match their edges. We provide a range of plausible radii. For each radius, two circles are extracted and we finally keep the five most prominent candidates. The result shows that coin positions are well-detected.
