In this paper, we propose shape features that are based on MPEG-4 compressed domain shape information. These shape features can be used for efficient retrieval of both MPEG-4 video objects and video object planes. The proposed shape descriptors are invariant of the shape size, translation, and rotation. Because the shape descriptors are computed using the MPEG-4 compressed domain information, extraction of the features require minimal computation time
