摘要

The JPEG-LS with rate control mechanism is widely applied in buffer and bandwidth managements. In existing works, the compression ratio (CR) gradually reaches target compression ratio (TCR) based on the adjustment of information loss level at row by row. However, the CRfluctuation is induced and limits its performance in bandwidth-efficiency applications. In this paper, the proposed segment-based rate control (SBRC), which comprises progressive adjustment of information loss level and scaling just noticeable distortion (JND) model, is applied in JPEG-LS. Experiment results show that the CRfluctuation can be efficiently reduced and visual quality is also maintained.
