A New Mean Residual Fractal Image Coding With Fast Decoding
一种基于去均值的加速收敛的分形压缩算法

A new mean residual fractal image coding algorithm with fast decoding is proposed in this paper. Theoretical analysis and experimental tests have shown that the iteration times in decoding process are reduced significantly with an improved PSNR value. In addition, the proposed new method is further combined with adaptive quadtree partition to obtain a good trade off between compression ratio and image quality. Superior coding perfermance is confirmed by simulation tests as compared to the conventional fractal coding.
