一种新型的虹膜定位算法

New Algorithm of Iris Location

针对虹膜图像自身的特点,利用信息论中最大熵的方法进行阈值选取,提出了先将其分成三个灰度等级以最大限度的消除干扰信息,然后进行快速定位的新方法。实验结果表明,该方法具有很好的定位效果。

According to the characteristics of iris image and the theory of the most entropy, this paper proposes a new method of translating iris image into three gradations and realizing its fast location. Experiments show that this method can produce good results.
