Moktari Mostofa, Salman Mohamadi, Jeremy Dawson, Nasser M. Nasrabadi

摘要:

近年来,交叉光谱虹膜识别已经成为一种很有前途的生物识别方法,以建立个人的身份。然而,匹配在不同光谱带(即,将可见光(VIS)虹膜探针与近红外(NIR)虹膜图像的图库相匹配,或反之亦然)与带内NIR匹配相比,显示出显著的性能下降。因此,在本文中,我们研究了一系列深度卷积生成对抗网络(DCGAN)架构,以进一步提高跨光谱虹膜识别方法的准确性。此外,与文献中现有的作品,我们引入了一个分辨率差异到经典的交叉光谱匹配问题域。我们已经开发了两种不同的技术,使用条件生成对抗网络(cGAN)作为骨干架构的跨光谱虹膜匹配。在第一种方法中,我们通过训练cGAN同时解决交叉分辨率和交叉光谱匹配问题,该cGAN将交叉分辨率和交叉光谱任务联合转换为相同的分辨率和相同的光谱。在第二种方法中,我们设计了一个耦合的生成对抗网络(cpGAN)架构,该架构由一对cGAN模块组成,该cGAN模块将VIS和NIR虹膜图像投影到低维嵌入域中,以确保来自同一受试者的两种虹膜模态的特征向量之间的最大成对相似性。

英文摘要:

In recent years, cross-spectral iris recognition has emerged as a promising biometric approach to establish the identity of individuals. However, matching iris images acquired at different spectral bands (i.e., matching a visible (VIS) iris probe to a gallery of near-infrared (NIR) iris images or vice versa) shows a significant performance degradation when compared to intraband NIR matching. Hence, in this paper, we have investigated a range of deep convolutional generative adversarial network (DCGAN) architectures to further improve the accuracy of cross-spectral iris recognition methods. Moreover, unlike the existing works in the literature, we introduce a resolution difference into the classical cross-spectral matching problem domain. We have developed two different techniques using the conditional generative adversarial network (cGAN) as a backbone architecture for cross-spectral iris matching. In the first approach, we simultaneously address the cross-resolution and cross-spectral matching problem by training a cGAN that jointly translates cross-resolution as well as cross-spectral tasks to the same resolution and within the same spectrum. In the second approach, we design a coupled generative adversarial network (cpGAN) architecture consisting of a pair of cGAN modules that project the VIS and NIR iris images into a low-dimensional embedding domain to ensure maximum pairwise similarity between the feature vectors from the two iris modalities of the same subject.
