该算法由变换组合优化、彩色分量加权、CSF滤波三部分组成。实验结果表明，在非常大的压缩比率范围下，该算法的客观质量和主观质量都优于JPEG2000有损变换算法和JPEG2000无损压缩算法。-Optimization of the algorithm by the transformation, color component weighted, CSF filtering of three parts. The results show that in the very large compression ratio range, the objective of the algorithm are better than the quality and subjective quality JPEG2000 detrimental transform algorithm and JPEG2000 lossless compression algorithm.
