摘　　要：虹膜识别技术由于与其它生物特征识别技术相比具有更高的准确率而一直备受关注。本文采用局部线性嵌入算法对虹膜样本进行训练,来提取虹膜纹理特征,并以最小距离分类器作为决策空间的判决准则。实验表明本文提出的虹膜识别方法取得了良好的识别效果。Iris recognition becomes a hot topic because it outperforms other biometric methods and can achieve a very goodrecognition performance. In this paper, a new iris recognition method is proposed, which adopts locally linear embedding(LLE) to train samples of iris images and extract iris texture feature, then the discriminating criterion in the discriminant spaceis determined by the minimum distance classifier. In addition, experiments show that the results on the iris database in computerare achieved.
