| 摘 要： | 分形图像压缩方法由于其压缩比高、解压方法简单等原因受到了越来越多的重视，但它的压缩质量不是很令人满意，本文在传统算法的基础上对通过定义域块收缩得到的代码本块提出修正算法，证明了该修正算法获得的近似匹配块的均方根误差小于原有的匹配块的误差，本文还对代码本块像素强度值提供了校正方法，使得还原图像在局部上能够更近似于原图像。 |

| Abstract: | The interest in the subject of fractal image compression seems to have grown during recent years because of its high ratio and simple decoding. However, the quality of fractal image compression is not very well. This paper proposes a revised algorithm based on the traditional algorithm by revising some codebooks. And we proved that the rms error of the revised algorithm is reduced. Furthermore, we improves the pixel intensities of codebooks and make the decoded image more like the original image. |
