摘要:

人脸反欺骗(FAS)在保护人脸识别系统免受呈现攻击方面起着至关重要的作用。现有的多模态FAS方法依赖于堆叠的香草卷积,其在描述来自模态的详细内在信息方面很弱,并且当域移位(例如,交叉攻击和跨种族)。在本文中,我们将中心差分卷积网络(CDCN)\cite{yu2020searching}扩展到多模态版本,旨在捕获三种模态(RGB,深度和红外)之间的固有欺骗模式。同时,对基于单模态的CDCN进行了详细的研究。我们的方法获得了ChaLearn人脸反欺骗攻击检测论坛e@CVPR2020 \cite{liu2020cross}的“跟踪多模态”第一名以及”跟踪单模态(RGB)“第二名。我们最终提交的产品在“Track Multi-Modal”和“Track Single-Modal(RGB)"中分别获得1.02 $\pm$ 0.59\%和4.84 $\pm$ 1.79\% ACER。代码可以在{https://github.com/ZitongYu/CDCN}上找到。

英文摘要:

Face anti-spoofing (FAS) plays a vital role in securing face recognition systems from presentation attacks. Existing multi-modal FAS methods rely on stacked vanilla convolutions, which is weak in describing detailed intrinsic information from modalities and easily being ineffective when the domain shifts (e.g., cross attack and cross ethnicity). In this paper, we extend the central difference convolutional networks (CDCN) \cite{yu2020searching} to a multi-modal version, intending to capture intrinsic spoofing patterns among three modalities (RGB, depth and infrared). Meanwhile, we also give an elaborate study about single-modal based CDCN. Our approach won the first place in "Track Multi-Modal" as well as the second place in "Track Single-Modal (RGB)" of ChaLearn Face Anti-spoofing Attack Detection Challenge@CVPR2020 \cite{liu2020cross}. Our final submission obtains 1.02$\pm$0.59\% and 4.84$\pm$1.79\% ACER in "Track Multi-Modal" and "Track Single-Modal (RGB)", respectively. The codes are available at{https://github.com/ZitongYu/CDCN}.
