Privacy-preserving Social Distance Monitoring on Microcontrollers with Low-Resolution Infrared Sensors and CNNs. (arXiv:2204.10541v1 [cs.LG])

Low-resolution infrared (IR) array sensors offer a low-cost, low-power, and
privacy-preserving alternative to optical cameras and smartphones/wearables for
social distance monitoring in indoor spaces, permitting the recognition of
basic shapes, without revealing the personal details of individuals. In this
work, we demonstrate that an accurate detection of social distance violations
can be achieved processing the raw output of a 8x8 IR array sensor with a
small-sized Convolutional Neural Network (CNN). Furthermore, the CNN can be
executed directly on a Microcontroller …
