| Abstract: | Multi mode fast image compression method based on standard image (MFS) is an improved version of fractal image compression method based on iterated function systems.Based on the analysis of the strong and weak points of MFS,a new image compression method named MNS (multi mode image compression method based on normalized standard image) has been developed.In compare with MFS,MNS is not only faster in compression speed,but also better in restored image quality.The restored image quality of MNS is better than that of JPEG's in compression ratio equal four. |
