摘要
提出的快速搜索算法的分形图像压缩技术,将搜索到的非重复的定义域块,再快速排除,并能在计算量较小的情况下判断是否再继续延伸到其他可能的定义域区。该方法获得更好的图像恢复质量(PNSR约提高0.2~1dB)及较少的编码时间。
In this paper,we proposed the Fast Searching Scheme,It colleted non-repeat blocks and to eliminate rapidly.Then,others possible blocks determined whether it extended continuously or not without cost.Experimental results show that the method has a better image quality and spend less time than others.The PSNR increases 0.2~1 dB.
