摘要
设计了一种基于区域划分的分形图像压缩方法 ,这种方法根据拼贴误差最小原则合并相邻子区域对 ,将图像划分为一些具有局部自相似性的不规则形状区域。与传统的基于规则形状块划分的分形图像压缩方法相比较 ,这种方法在相同的信噪比下可以达到更高的压缩比 。
A method of the fractal image compression based on region partition is designed, which is used to merge the neighboring sub-regional pairs according to the principle of the least collage errors. Compared to the present widely used fractal image compression method based on block partition, a higher compression ratio can be achieved compared to the same sign to noise ratio.
