摘要： 为了得到可变的位率,在分形图像压缩中经常采用四叉树分割方法。该文提出了一种基于模糊积分的剖分决策函数——模糊均差,可以在改善图像编码质量的同时增加编码速度。也分析比较了其他一些常用的剖分决策函数。

Abstract: Quadtree partitions are often used in fractal image compression to achieve variable bit rates. This paper proposes a fuzzy integral based split decision function——fuzzy mean error that can improve image coding quality and speed up the encoding process. Moreover, other commonly used split decision functions are analyzed.
