摘要:

由于人脸服务场景的复杂性和人脸呈现攻击模式的多样性,人脸反欺骗(FAS)是一个具有挑战性的问题。特别是当采集到的图像分辨率低、模糊、来自不同的域时,FAS的性能会显著下降。现有的多模态FAS数据集很少关注部署场景下的跨域问题,不利于模型性能的研究。为了解决这些问题,我们探讨了多模态相机之间的细粒度差异,并构建了一个跨域的多模态FAS数据集下的监控场景称为GREAT-FASD-S。此外,我们提出了一个基于注意力的人脸反欺骗网络与特征增强(AFA),以解决FAS对低质量的人脸图像。它由深度可分离注意模块(DAM)和基于多模态的特征扩充模块(MFAM)组成。我们的模型可以在CASIA-SURF数据集和我们提出的GREAT-FASD-S数据集上实现最先进的性能。

英文摘要:

Face Anti-spoofing (FAS) is a challenging problem due to complex serving scenarios and diverse face presentation attack patterns. Especially when captured images are low-resolution, blurry, and coming from different domains, the performance of FAS will degrade significantly. The existing multi-modal FAS datasets rarely pay attention to the cross-domain problems under deployment scenarios, which is not conducive to the study of model performance. To solve these problems, we explore the fine-grained differences between multi-modal cameras and construct a cross-domain multi-modal FAS dataset under surveillance scenarios called GREAT-FASD-S. Besides, we propose an Attention based Face Anti-spoofing network with Feature Augment (AFA) to solve the FAS towards low-quality face images. It consists of the depthwise separable attention module (DAM) and the multi-modal based feature augment module (MFAM). Our model can achieve state-of-the-art performance on the CASIA-SURF dataset and our proposed GREAT-FASD-S dataset.
