摘要
由于虹膜具有惟一性、稳定性、不可更改性等优点,虹膜识别已经成为生物特征身份识别领域中的研究热点。为了简化特征提取方法并提高虹膜识别的准确性,提出一种基于相位一致性的虹膜识别方法。该方法利用相位一致性所具有的较强特征检测能力,提取虹膜纹理的边缘点标记纹理的位置信息,将位置特征作为虹膜纹理的可区分性特征实现虹膜识别。在CASIA-IrisV3-Interval图像库上进行实验的结果证明,该方法是可行的,也是有效的,并且具有较高的识别准确性。
Iris recognition has become a research hot-spot in the biometrics recognition filed,because the iris has the properties of unique,stable,unchangeable.an iris recognition method based on phase congruency is proposed,to simplify the method of feature extraction and improre the accuracy of iris recognition,the edge points of iris veins were extracted to mark the location information of iris by utilizing the strong ability for feature detection of phase congruency.It also considers the location feature as the distinguishable feature of iris veins.Experimental results on CASIA-IrisV3-Interval image database demonstrate that the proposed method is feasible and effective,and it has high recognition accuracy.
