摘要:

在没有疫苗或药物阻止COVID-19的情况下,减缓冠状病毒传播和减少医疗负担的有效方法之一是戴口罩。然而,为了强制在公共场所使用口罩或遮盖物,需要额外的人力资源,这是乏味和注意力密集的。为了使监控过程自动化,其中一个有前途的解决方案是利用现有的目标检测模型来检测有面具或没有面具的人脸。因此,安全人员不必盯着监控设备或人群,只需处理因检测到未戴口罩的面部而触发的警报。现有的目标检测模型通常侧重于设计基于CNN的网络架构来提取区分性特征。然而,人脸面具检测的训练数据集的大小是小的,而有和没有面具的人脸之间的差异是微妙的。因此,在本文中,我们提出了一个面具检测框架,使用上下文注意模块,使前馈卷积神经网络的有效注意,通过调整其注意力图特征细化。此外,我们进一步提出了一个无锚检测器与三重一致性表示学习通过整合一致性损失和三重损失处理小规模的训练数据和掩模和遮挡之间的相似性。大量的实验结果表明,我们的方法优于其他国家的最先进的方法。源代码作为公共下载发布,以改善公众健康在www.example.com。

英文摘要:

In the absence of vaccines or medicines to stop COVID-19, one of the effective methods to slow the spread of the coronavirus and reduce the overloading of healthcare is to wear a face mask. Nevertheless, to mandate the use of face masks or coverings in public areas, additional human resources are required, which is tedious and attention-intensive. To automate the monitoring process, one of the promising solutions is to leverage existing object detection models to detect the faces with or without masks. As such, security officers do not have to stare at the monitoring devices or crowds, and only have to deal with the alerts triggered by the detection of faces without masks. Existing object detection models usually focus on designing the CNN-based network architectures for extracting discriminative features. However, the size of training datasets of face mask detection is small, while the difference between faces with and without masks is subtle. Therefore, in this paper, we propose a face mask detection framework that uses the context attention module to enable the effective attention of the feed-forward convolution neural network by adapting their attention maps feature refinement. Moreover, we further propose an anchor-free detector with Triplet-Consistency Representation Learning by integrating the consistency loss and the triplet loss to deal with the small-scale training data and the similarity between masks and occlusions. Extensive experimental results show that our method outperforms the other state-of-the-art methods.
