摘要: This paper proposes a new contour based shape matching approach capable of recognizing partially occluded objects in images. The process can be divided into the following steps: region formation from low level color image segmentation, B-spline filtering and feature point extraction, correspondence determination, least square estimation affine transformation parameters, similarity measuring. Once is established, information retained using hierarchical content description scheme, enabling expedient object retrieval at later time.
