摘　　要：虹膜识别是近年来新兴的生物识别方法,虹膜识别以其简单的算法、快速的识别以及较低的错误识别率逐渐被应用到许多重要的领域。通过分析现有Daugman算法的局限性,提出一种新型的改进的虹膜识别算法,该算法结合积分微分算子与哈夫变换来进行虹膜定位,然后利用多通Gabor滤波提取虹膜特征。通过实验证明,该算法有效地克服了Daugman算法中非散射人工光源引起的亮点效应,同时也增强了虹膜识别的实用性和适应性。Iris recognition which is a bio-identification method is emerging in recent years,iris recognition algorithm is gradually being applied to many important areas by its simple,rapid identification and lower error recognition rate. Daugman algorithms by analyzing the limitations of existing proposed a new improved iris recognition algorithm,which combines integral-differential operator and Hough transform to carry out iris location,and then using multi-pass Gabor filters extract iris feature. Experiments show that the algorithm effectively overcome the Daugman algorithms Central Africa bright spot caused by scattering of artificial light effects,but also enhance the practicality and adaptability of iris recognition.
