摘　　要：本文在充分考虑人眼视觉特性的基础上 ,针对可视电话、视频电视会议等领域经常出现的视频头肩序列图像 ,提出了一种面向人脸检测与跟踪的视频分级编码方法 ,在极低比特率的情况下 ,接收端仍能获得视觉质量较好的恢复序列图像 .Aiming at head and shoulder video sequences often showed in those fields such as visual telephone,video conference and etc.,with human visual characterstic to best advantage,a scalable video coding method based on human face detection and tracing is presented in this paper.The reconstructed image sequences with good subjective quality can be obtained with very low bitrate.
