摘要:

这项工作解决了比较在不同光谱中捕获的眼周图像的挑战,已知与在相同光谱中操作相比,这会产生性能的显著下降。我们建议使用条件生成对抗网络,经过训练可以在可见光和近红外光谱之间转换眼周图像,以便在同一光谱中进行生物识别验证。所提出的设置允许使用现有的特征方法,通常被优化为在单个光谱中操作。识别实验是使用一些现成的眼周比较器的基础上手工制作的功能和CNN描述符。使用香港理工大学交叉光谱虹膜图像数据库(理大)作为基准数据集,我们的实验表明,交叉光谱性能显着提高,如果两个图像被转换为相同的光谱,在不同的光谱图像中提取的匹配功能相比。除此之外,我们还基于ResNet 50架构微调了CNN,获得了EER= 1%,GAR> 99%@FAR = 1%的跨光谱眼周性能,这与PolyU数据库的最新技术相当。

英文摘要:

This work addresses the challenge of comparing periocular images captured in different spectra, which is known to produce significant drops in performance in comparison to operating in the same spectrum. We propose the use of Conditional Generative Adversarial Networks, trained to con-vert periocular images between visible and near-infrared spectra, so that biometric verification is carried out in the same spectrum. The proposed setup allows the use of existing feature methods typically optimized to operate in a single spectrum. Recognition experiments are done using a number of off-the-shelf periocular comparators based both on hand-crafted features and CNN descriptors. Using the Hong Kong Polytechnic University Cross-Spectral Iris Images Database (PolyU) as benchmark dataset, our experiments show that cross-spectral performance is substantially improved if both images are converted to the same spectrum, in comparison to matching features extracted from images in different spectra. In addition to this, we fine-tune a CNN based on the ResNet50 architecture, obtaining a cross-spectral periocular performance of EER=1%, and GAR>99% @ FAR=1%, which is comparable to the state-of-the-art with the PolyU database.
