The use of stereo and motion in a generic object-based coder

摘要

Current developments of object-based coders target small image formats, low bit-rate and videophone applications with head-and-shoulders scenes. An object-based coder which can be used for any type of scene and can provide better picture quality than MPEG-2 at the same bit-rate is proposed in this paper. It is a high-quality object-based coder which aims to introduce the concept of object-based coding in quality-picture applications. The coder uses motion and stereo information throughout for image analysis and synthesis, and object ordering. The coder can be extended to a stereoscopic coder with only minor modifications. Results using CCIR 601 stereoscopic image sequences shot within RACE DISTIMA are presented.
