摘要 提出一种能精确控制各编码层码率的JPEG2000感兴趣区域编码算法,对整个图像进行统一的JPEG2000编码,分别统计背景、感兴趣区域各自分配到的比特数。利用率失真函数的凸函数特性,在总码率恒定的条件下调整上述两区域分配的比特数,使得感兴趣区域获得优于背景区域的编码质量。该算法中感兴趣区域及其优先级均可动态改变,生成码流与标准完全兼容。 An algorithm for Region Of Interest（ROI） coding in JPEG2000, which can achieve the accurate bitrate control in each layer, is proposed in this paper. It codes the image without concerning the ROI. Then it counts out the bits allocated for the background and the ROI respectively. Under the constraints of the total bitrate, the proposal method reallocates the bits for both regions above. By this way, the ROI can achieve higher performance than the background due to the convex characteristic of rate-distortion function. Both the ROI and its priority can be modified in the algorithm, and the algorithm produces a fully compliant JPEG2000 code stream.
