Face recognition has become a significant challenge today since an increasing number of individuals wear masks to avoid infection with the novel coronavirus or Covid-19. Due to its rapid proliferation, it has garnered growing attention. The technique proposed in this chapter seeks to produce unconstrained generic actions in the video. Conventional anomaly detection is difficult because computationally expensive characteristics cannot be employed directly, owing to the necessity for real-time processing. Even before activities are completely seen, they must be located and classified. This paper proposes an expanded Mask R-CNN (Ex-Mask R-CNN) architecture that overcomes these issues. High accuracy is achieved by using robust convolutional neural network (CNN)-based features. The technique consists of two steps. First, a video surveillance algorithm is employed to determine whether or not a human is wearing a mask. Second, Multi-CNN forecasts the frame's suspicious conventional abnormality of people. Experiments on tough datasets indicate that our approach outperforms state-of-the-art online traditional detection of anomaly systems while maintaining the real-time efficiency of existing classifiers.
如今,人脸识别已成为一项重大挑战,因为越来越多的人戴口罩以避免感染新型冠状病毒或新冠病毒。由于其迅速传播,它已受到越来越多的关注。本章提出的技术旨在在视频中产生无约束的通用动作。传统的异常检测很困难,因为由于需要实时处理,计算成本高昂的特征不能直接使用。甚至在活动完全被看到之前,就必须对其进行定位和分类。本文提出了一种扩展的Mask R-CNN(Ex-Mask R-CNN)架构来克服这些问题。通过使用基于强大卷积神经网络(CNN)的特征实现了高精度。该技术包括两个步骤。首先,采用视频监控算法来确定一个人是否戴着口罩。其次,多CNN预测帧中人物可疑的传统异常情况。在具有挑战性的数据集上进行的实验表明,我们的方法在保持现有分类器实时效率的同时,优于当前最先进的在线传统异常检测系统。
