| Abstract(in English) | In this paper we propose an algorithm to detect the symmetry axes of a symmetrical figure using the random sampling and voting procedures. The proposing algorithm is stable against occulusion and noizes. First, we randomly select a pair of triplet points from the figure boundary. Next, if a pair of these points mutually form congruence triangles, we compute the rotated angle and vote it to the accumulator space. After the sufficient number of iteration for sampling and voting, we detect peaks in the accumulator space. These peaks appear periodically according to the folding number of a symmetrical figure. Detecting the folding number and its center of rotation, it is possible to recover occluded parts by rotating figures according to the folding number. This algorithm detects symmetry of figure and recovers occluded parts. |
