虹膜纹理编码身份识别技术

利用人眼特征进行身份识别的技术作为新兴的身份鉴定方法已开始用于网络交易，银行，海关等机构，本文就人眼身份识别的关键技术－虹膜纹理编码进行了讨论。作者通过分析影响识别性能的几个关键问题，提出了傅利叶－小波混合变换法对虹膜编码，并给出了在利用编码结果组成的数据库对输入图像进行快速匹配或查询的方法。实验结果表明该方法能有效地降低图像采集时平移，旋转，反光带来的编码误差。

IDENTITY RECOGNITION TECHNIQUE BASED ON IRIS TEXTURE CODING

Recently, a new identity recognition method based on the character of human eyes has been used in network trade, bank and custom. In this paper, the author discusses the key technique of iris recognition, texture encoding of iris. According to the analysis of several key elements that affect the recognition performance, a Fourier - Wavelet encoding method is presented as well as the quick search method using the encoding data in database. Results of the experiments show that this method can efficiently reduce the coding error due to shift rotation and glisten.
