The global paradigm shift in public health monitoring has cemented automated face mask detection as a critical component of smart-city infrastructure and bio-surveillance ecosystems. While initially catalyzed by pandemic-era mandates, the enduring need for non-intrusive compliance tracking in high-density public spaces demands highly accurate, privacy-preserving, and computationally efficient computer vision solutions. Despite significant advancements in deep learning, existing object detection frameworks frequently struggle with the dichotomy of high-precision classification and the stringent low-latency constraints of edge-computing devices. Heavyweight models suffer from processing bottlenecks on standard closed-circuit television (CCTV) hardware, whereas overly simplified models fail to account for complex optical variables such as dynamic lighting, dense crowd occlusion, and diverse facial orientations.
To address these critical limitations, this paper proposes a highly optimized, real-time face mask detection framework that synergizes the rapid localization capabilities of the You Only Look Once (YOLO) architecture with the lightweight feature extraction efficiency of a MobileNetV2 backbone. By mathematically streamlining convolutional operations and bounding-box regression, the proposed hybrid pipeline is engineered for seamless deployment on low-cost Internet of Things (IoT) nodes without relying on cloud-based processing. Furthermore, this research systematically synthesizes 25 pivotal studies, mapping the evolutionary trajectory of facial occlusion detection from early heuristic classifiers to modern single-stage convolutional neural networks, thereby providing a comprehensive theoretical foundation.
Empirical evaluations on a withheld testing dataset demonstrate that the MobileNetV2-backed classifier achieves an exceptional validation accuracy of 97.5%. Concurrently, the system sustains an average inference speed of 45 frames per second on commercial graphical processing units, unequivocally satisfying real-time processing thresholds. Ultimately, this framework provides a scalable, robust blueprint for integrating localized artificial intelligence into permanent, proactive public health architectures.
