| 摘 要： | 提出一种基于分形集和迭代函数系统的多层子块匹配图像压缩算法．通过高层次的子块匹配结果限定低层次子块的搜索范围，多层子块匹配能减少搜索复杂度，实验结果表明该算法能够在保证图像质量的情况下取得较好的压缩效果．

| Abstract: | A new multilevel blocks-matching algorithm for image compression and decompression scheme is presented which is based on fractal set and quickly iteration function system(IFS). The searching range is restricted by the higher-level blocks, and thus multilevel blocks-matching can reduce the searching complexity. The computational results showed that the approach is of high performance in improving image compression based on retaining image quality. |
