摘要
利用图象子波分解空间的自相似性,用分形块编码方法,由低分辨率细节构造高分辨率细节,提出了一种新的子波与分形结合压缩编码方法,实验结果表明,这种方法可以在高压缩比的情况对图象进行快速压缩。
In this paper,based on the self-similarity of the image wavelet decomposion spaces,a new kind of coding method about combining wavelet with fraction is proposed by using of the method of fractral block coding,and constructing the details from low resolution to high resolution.The simulation result shows the efficience of the fast compressing image in the high compression ratio.
