| 摘 要:利用虹膜图像固有的对称特性,提出了基于对称性的快速分形虹膜图像特征区域的压缩算法;
通过虹膜图像特征区域边缘的定位,确定对称轴,然后对于一值域图像块,与其匹配的定义域块被限定在其
对称区域中,从而可减少定义域块的搜索范围,加快分形编码速度,最终达到加速虹膜图像压缩目的。 |

| Abstract: |
| Abstract:A fast comp ression algorithm of Iris image interest region based on symmetry and fractal coding is
p roposed by using its inherent symmetry feature. The matched domain image blocks are restricted in the symmetri2
cal region for a range block, which can decrease the searching region of the blocks, then speed up the fractal enco2
ding, at last, accelerate the Iris image comp ression. |
