摘　　要：本文在图象边缘信息的基础上，建立了一种新的运动图象信源模型．与经典方法相比：该信源模型不同于离散随机场．建立该信源模型的方法比较简单可靠，也不需要任何图象的先验知识．它能成功地用于运动图象编码，编码方法也突破了传统的波形编码范畴．从广义上说，它属于模型基编码方法．n this paper, a new source model for image sequence was established based on edge information. The model isn't a traditional version since the foundation is not same as discrete random field. The method to construct the model is relatively simple and reliable. No prior knowledge is needed for modeling. While the new one applied in image sequence encoding successfully, the coding is beyond the range of classical waveformbased concept. Generally, it's a type of modelbased coding.
