Google Edge TPU上的实时遮罩检测

在COVID-19爆发后，自动检测人们是否戴着口罩以降低一线工人的风险已变得很重要。此外，在本地处理用户数据是解决隐私和网络带宽问题的好方法。..

Real-time Mask Detection on Google Edge TPU

After the COVID-19 outbreak, it has become important to automatically detect whether people are wearing masks in order to reduce risk of front-line workers. In addition, processing user data locally is a great way to address both privacy and network bandwidth issues.In this paper, we present a light-weighted model for detecting whether people in a particular area wear masks, which can also be deployed on Coral Dev Board, a commercially available development board containing Google Edge TPU. Our approach combines the object detecting network based on MobileNetV2 plus SSD and the quantization scheme for integer-only hardware. As a result, the lighter model in the Edge TPU has a significantly lower latency which is more appropriate for real-time execution while maintaining accuracy comparable to a floating point device.
