Abstract

This paper proposes a new contour based shape matching approach capable of recognizing partially occluded objects in images. There are tow major steps in the recognition process of partially occluded objects: 1) feature extraction, and 2) similarity matching. The features for a candidate image region are the contour for better accuracy in curvature estimation. To determine the similarity between a candidate region and an object template, we compute the Hausdorff distance from the contour of the candidate image region to that of the template, where the region contour has been mapped into the template domain. Once a match is established, the information is retained using a hierarchical content description scheme, enabling expedient object based image retrieval at a later time.
