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小波编码方法 ,在极低比特率下 ,解码端仍能获得视觉质量较好的恢复序列图像。
A video hierarchical wavelet coding method for face detection and tracking has been proposed for the video head-shoulders sequence images frequently appearing in the fields of video telephony and video teleconferencing. At very low bit-rate, the decoder can still obtain the visual quality Better recovery sequence images.
