摘要
在深入分析PIFS分形图像压缩编码原理的基础上,明确了影响分形编码速度的四个因素,分别针对各因素提出了改进方法。实验证明本文方法在提高编码速度和压缩比方面是有效的。
Based on further analysis of PIFS fractal image encoding algorithm,this paper presents four factors that influence fractal encoding speed.For these factors,several improved methods are proposed.Experiments＇ results show the efficiency of the proposed hybrid approach in encoding speed and compression ratio.
