| 摘 要： | 提出了一种简单易行的虹膜定位算法，该算法是在对虹膜粗略处理的基础上，对内边界的采用了向坐标轴投影的方法；对于外边界采用了寻找扫描线上信息量最小的点，并用相应的匹配模板进行匹配，以便去掉由于噪声的干扰而找到的错误点，从而确定外边界和中心；实验证明了该算法的合理性。 |

| Abstract: | A new and simple iris location method was proposed. The algorithm includes the location of inside and outside of the iris. Based on the rough process of the iris image, for the inside location the author takes the method of the projection to the coordinate, and for the outside the author looks for the point which the content of information is least on the scanning line. For the distribution of the yawp for example eyelash, the point which we choose is not only one. The author abandons the wrong point using the corresponding templates. It is proved that the algorithm is feasible through experiments. |
