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。
Based on the deep research on the principle of fractal image coding, this paper proposes a fast search method based on “the variance relation between the region block and the transformed region block” - R-D search method. Compared with the JFB search method, the R-D search method can improve the encoding speed by about 2 times under the conditions of reconstructing the image quality.
