中文摘要：
虹膜识别技术是一种非侵犯性的身份鉴别技术．文中探讨了虹膜识别系统，该系统分为虹膜图像的捕获、图像的预处理、特征提取和匹配几大部分；并在此基础上提出了A动虹膜识别算法和虹膜图像的校准技术，最后用基于相位匹配和二维傅里叶变换的幅值差方法来确定虹膜图像的匹配结果．实验证明．该方法运算速度较快，识别效果良好．
英文摘要：
Iris recognition is a noninvasive technique for human identification. An iris recognition system is presented in this paper. It is composed of iris image acquisition,iris image preprocessing, feature extraction and matching. This paper also proposes an algorithm for automated iris recognition and a method for recti- fication of iris image. The matching result is measured by disparity of the range based on 2D-FFT. The experimental results show that the method has a high speed. The recognition results are satisfactory.
