| Abstract: |
The Rate-Distortion Optimization (RDO) technique plays an important role in JPEG2000 coding systems. In this paper, detailed analysis and parallel technique for RDO is presented. Differing from the usual or so far improved RDO techniques, the proposed technique can process each bit-plane’s code-stream and rate-distortion pairs independently, which provides parallel processing and is easy for hardware implementation. It can speed up the RDO processing and meets the requirement of the parallel JPEG2000 encoder. Experiment results show that the PSNR performance is optimal and the coding speed satisfies the requirement of the high resolution real-time applications. |
