摘要：
Shape representation using Curvature scale space descriptor (CSSD), which is adopted as MPEG7 standard, has been widely used in image retrieval. In this paper, a new similarity measure, called Polar Curvature Scale Space (PCSS) measure, is proposed to improve the performance of shape retrieval. In our proposal, the distance between query and gallery images is calculated on a circular vector map, which is converted from the original canonical CSS (CCSS) descriptor space. Comparative experiment by using a marine animal database showed that the PCSS outputs better matching images than that of CCSS in general.
