论文摘要

这些近年来的大流行导致人们在公共场所戴着保护口罩的人们急剧增加。这对目前正在绩效下降的面部识别技术普遍地使用面部识别技术提出了明显的挑战。解决该问题的一种方法是将恢复方法恢复为预处理步骤。当前面对重建和操纵的方法利用了对面部歧管建模的能力,但往往是通用的。我们介绍了一种特定于从戴着面具的同一个人的图像中恢复面部图像的方法。我们通过设计一种专门的GAN反转方法来做到这一点,该方法基于学习揭示编码器的适当损失。通过广泛的实验,我们表明该方法可有效揭示面部图像。此外,我们还表明,基于多个面部识别基准数据集的身份信息可以很好地保留,以提高面部验证性能。

The pandemic of these very recent years has led to a dramatic increase in people wearing protective masks in public venues. This poses obvious challenges to the pervasive use of face recognition technology that now is suffering a decline in performance. One way to address the problem is to revert to face recovery methods as a preprocessing step. Current approaches to face reconstruction and manipulation leverage the ability to model the face manifold, but tend to be generic. We introduce a method that is specific for the recovery of the face image from an image of the same individual wearing a mask. We do so by designing a specialized GAN inversion method, based on an appropriate set of losses for learning an unmasking encoder. With extensive experiments, we show that the approach is effective at unmasking face images. In addition, we also show that the identity information is preserved sufficiently well to improve face verification performance based on several face recognition benchmark datasets.
