Abstract

Different source models for content-based video coding are presented. An object-based analysis-synthesis coder describes video objects by means of motion, shape and texture parameters. In contrast to block-based coding, the representation of arbitrarily shaped objects in a real scene is possible. Using knowledge about the scene content and about the object´s behavior, object-based coding is extended to knowledge-based coding and semantic coding, respectively. Compared with other content-based video coding concepts like MBASIC and MPEG-4, the above mentioned coders provide an integrated and more efficient framework for coding video using 3D source models
