基于预优投票的虹膜定位算法

针对传统虹膜定位算法定位速度慢、受眼睑、睫毛等遮挡影响的不足,本文基于投票竞选和圆的几何特性,提出基于预优投票竞选策略的虹膜圆检测算法。为减少盲目搜索和克服眼睑、睫毛等遮挡影响,建立了逐步求精的实施方案,从而形成一个快速有效、鲁棒性强的虹膜定位算法。基于JLU-IRIS虹膜库,从定位速度和定位精度两方面评价本文构造算法性能,将本文构造算法与积分微分算子法、Hough圆检测算法进行了对比测试。实验结果表明,本文方法具有快速、鲁棒性强的特点。

Iris location algorithm based preconditioning voting

Traditional iris location algorithms that have drawbacks of slow locating and partial occlusion influences such as eyelids,eyelashes and so on,the paper presented a preconditioning voting circle detection algorithm based on preconditioning voting and circle geometry property.In additional,in order to reduce the computation and effect by partial occlusion,such as eyelid,eyelashes etc,the iris boundaries are localized,using a coarse-to-fine strategy,in regions of interest.In experiments,the proposed method is...
