An efficient approach for circular shape target recovery

In this paper we propose an efficient approach for circular shape target recovery. The method makes use of the conterminous set of edge segments, or contour segments, instead of the huge edge points as traditional detectors do. First, the proposed approach computes the contour in a given image, which is then converted into contour segments at high curvature points. Then, by calculating the reinforcement of each virtual circle generated from three selected points on every contour segment, we can define which circles are really represented in the image. The experimental results are obtained in both single and multiple circular target objects.
