Rate Control for Motion JPEG2000 Using Correlation Prediction
Jun Yan Hou, Xiangzhong Fang, Rong Hou · 2006
Motion JPEG2000 has been widely used for its fine scalability with bit stream and its efficiency. A single scalable bitstream can provide precise rate control for variable bitrate (VBR) traffic. This paper presents an algorithm that makes use of correlation among the video frames to get consistent quality. By using one frame's distortion-rate to predict the next several frames' distortion-rate values, according to correlation among frames, we use only a few buffers to achieve highly consistent quality which used to use many buffers to achieve. Experimental results using motion JPEG2000 demonstrate substantial benefits.
