Xiaoyan Wu · Jisuanji gongcheng · 2010
To overcome the long encoding time of fractal image coding,this paper uses a fast fractal image encoding method based on two-norm,and improves it by using the error formula,which can derive an inequality of block's variance. This inequality is the basis to kick out the dismatched domain block,it can reduce the computational. Experimental results show that,compared with the two-norm method,the proposed algorithm improves the encoding speed,while provides the same image quality.
