How Circle Hough Transform works

In this video I explain how Circle Hough Transform works, by creating an accumulator for every edge detected (using Canny algorithm) in the original image. The accumulator corresponds always to a specific radius size, therefore it only works for circles with this size. For new radius, a new accumulator should be computed. The algorithm was based on the Wikipedia (https://en.wikipedia.org/wiki/Circle_...) adapted for a single radius, because in the original algorithm, all radius are computed.
