| 摘 要： | 将预处理后的虹膜图像分成64幅子块，并分别进行特征提取，然后按顺序提取每幅子图像完整的相位信息，建立相位特征向量，最后通过对特征向量进行内积运算获得虹膜样本之间的归一化分类距离。实验结果表明，该算法思路简洁，识别效果好，为虹膜分类研究提供了一种新的参考途径。

| Abstract: | The preprocessed iris image is divided into 64 sub-blocks，and the iris features are extracted respectively.The complete phase information of the features is extracted to establish the feature vector of iris，and then the normalized classification distance of iris samples is obtained by plot operation.The experiment shows that the idea of the algorithm is concise and reasonable，and its recognition effect is better.What’s more，it also offers a new way for iris classification research. |

| Keywords: | feature extraction phase correlation iris recognition classification distance |
