Enhanced Video Representation Using Objects

Object-based video representations such as MPEG-4 have opened up new possibilities for video content access and manipulation. In this paper, we present a new objectbased video representation paradigm, using appearance spaces. Our scheme enables fully automated extraction of semantic video objects for a class of sequences, and the development of a compressed, highly flexible representation of the video sequence based on extracted content. Our video representation supports content-based retrieval, as well as numerous enhanced features such as hyperlinking of videos, motion-icons for video browsing, automatic annotation, content-authoring facilities and se-
