| 摘 要： | 针对现有的虹膜定位算法的局限性，提出了一种基于数学形态学的虹膜定位算法。内圆定位是利用二值图像形态学的方法提取瞳孔的圆心和半径。外圆的定位用形态学进行边缘提取与Hough变换相结合，确定外圆圆心及半径。实验证明了该算法的合理性和有效性。

| Abstract: | Aiming at the limit of location algorithm , a method of the iris localization based on the Mathematical Morphology is proposed . A morphological method for the binary images is used to extract the center of pupil and estimate its radius. The method of edge detection based on Mathematical Morphology and Hough transform is used to locate the outer edge of the iris. The experimental results show that our algorithm is rational and feasible. |
