WebThe Hough transform in its simplest form is a method to detect straight lines but it can also be used to detect circles or ellipses. The algorithm assumes that the edge is detected and it is robust against noise or missing points. Circle detection In the following example, the Hough transform is used to detect coin positions and match their edges.
