摘要
虹膜识别技术是一种非侵犯性的身份鉴别技术。论文跟踪研究了虹膜定位算法,针对其局限性,做了改进,提出了虹膜图像平滑的方法,并讨论了几何定位和梯度边缘检测相结合的定位方法,使虹膜定位更加迅速。实验结果表明,该方法提高了虹膜定位的速度,并有良好的鲁棒性。
Iris recognition is a noninvasive technique for human identification.In this paper,the current iris location al-gorithms are studied and have been made betterments according to their limitations.A new iris location approach com-bining geometry location and gray gradient edge detection is presented to increase the speed of iris location greatly.The experiment results show that the approach is good to the speed of iris location and robust.
