Abstract: Shape feature is an important visual feature. This paper proposes an approach based on multiscale representation and dynamic programming for the shape matching and recognition. Considering the changes of shape feature points in different scale, multiscale representation of contours is proposed. And the process of contour segmentation can adjust automatically while the amounts of noise and deformation change. It is robust with respect to noise, shape deformation and occlusion. This paper successfullies apply the matching algorithm to the task of pedestrian recognition in the night vision system with good results, also demonstrates the superiority of the proposed method over three traditional shape matching methods.
