Paper Abstract

This paper presents a new object-based video coding algorithm for very low bit-rate video transmission. The algorithm employs an object-based approach for motion compensation, so that block distortion does not appear. The moving objects are detected from local decoded pictures, so information regarding object contours is not sent to a decoder. This technique contributes to drastically reducing the code amount to be transmitted. Motion compensated prediction errors are encoded by transform coding, but only large error regions are encoded. Computer simulation results at 16 kbps show that the subjective quality for a decoded picture by this algorithm is substantially better than that of a conventional algorithm.
