论文摘要
在本文中，我们建议使用光学相干断层扫描（OCT）成像来解决虹膜表现攻击（PA）检测问题。我们通过比较其在传统的虹膜成像方式中的性能，即近红外（NIR）和可见频谱来评估其生存能力。 OCT成像提供了眼睛的横截面视图，而传统成像则提供了2D虹膜纹理信息。 PA检测是使用三种最先进的深度体系结构（VGG19，Resnet50和Densenet121）进行的，以区分三种成像方式中的每一个。实验是在2,169个善意的数据集，177眼和360个化妆品接触图像上进行的，使用所有三种成像方式在攻击（已知的PAS）和跨攻击（未知PAS）方案下获得。我们观察到有希望的结果，证明OCT是虹膜表现攻击检测的可行解决方案。
In this paper, we propose the use of Optical Coherence Tomography (OCT) imaging for the problem of iris presentation attack (PA) detection. We assess its viability by comparing its performance with respect to traditional iris imaging modalities, viz., near-infrared (NIR) and visible spectrum. OCT imaging provides a cross-sectional view of an eye, whereas traditional imaging provides 2D iris textural information. PA detection is performed using three state-of-the-art deep architectures (VGG19, ResNet50 and DenseNet121) to differentiate between bonafide and PA samples for each of the three imaging modalities. Experiments are performed on a dataset of 2,169 bonafide, 177 Van Dyke eyes and 360 cosmetic contact images acquired using all three imaging modalities under intra-attack (known PAs) and cross-attack (unknown PAs) scenarios. We observe promising results demonstrating OCT as a viable solution for iris presentation attack detection.
