摘要
在深入研究分形图象编码原理的基础上 ,提出一种基于“区域块与简单变换后的范围块之间方差关系”的快速搜索方法—— R- D搜索方法。与 JFB搜索方法相比 ,在重建图象质量相当的条件下 ,R- D搜索方法使编码速度大约提高 2倍。
After making an intensive study of the principle of fractal image coding,this paper presents a fast searching method named RD searching method,which is based on the relation between the variance of range block and that of simply transformed domain block.When the quality of reconstructed image is comparable to that of JFB searching method ,this one increases the encoding speed by about 2 times.
