| 摘要: |
| 为了提高二值图像的压缩比,采用自顶向下的编码方法,提出一种基于等腰直角三角形的分形图像压缩算法,并进行仿真实验。该算法对无损压缩的图像还原后与原图像没有差别,压缩比比一些无损压缩算法高,提高了压缩图像的压缩比。该算法在重构图像时不会产生水平与垂直边际效应,而且可以在有损压缩和无损压缩之间灵活切换。 |

| Abstract: |
| In order to improve the ratio of binary image compression,using top-dowm method of coding,bring forward a fractal image compression method based on isosceles right triangle,and simulated.After restoration,there is no difference between lossless compression image and original image,and improve the ratio of image compression.Using the algorithm to reconstruct the compressed image in a manner that does not have a marginal effect of horizontal and vertical,but also can switch between lossy compression and lossless compression. |
