| 摘 要： | 针对虹膜图像自身的特点,先利用最大熵的方法把虹膜图像分成3个灰度等级,使虹膜最大限度的呈现出内外边界,然后在此基础上运用Daugman提出的虹膜定位算法能更有效地定位虹膜.实验表明,该算法具有更好的定位效果.

| Abstract: | According to characteristics of the iris image and the principle of the maximum entropy,we first get the maximal edge of iris by translating the image into another which consists of three gradations;then apply the Daugman algorithm to locating iris.The experiments with this method show that this method has better effectiveness of location. |
