The searching computation of the best matched domain block is most heavy in the fractalencoding process.
在分形编码过程中,搜索值域块的最佳匹配的定义域块的计算量最大。

We further propose a possible fast hybrid fractalencoding algorithm which combines existing fast search methods, statistical normalization and frequency domain comparison.
Thus, encoding an image by fractal techniques consists of finding an appropriate contractive transformation whose fixed point is the best possible approximation of the original image.
