A QGIS Plugin to monitor proximities in surveillance videos

Quantum Geographic Information System (QGIS) is a topographical system that processes spatial data. Popular spatial algorithms such as spatial join, clipping, area computations and visualizations are implemented either as a basic support or through additional Plugins designed with Python modules. These features are not yet available for video input in QGIS. With the current Covid-19 pandemic outbreak the non-pharmaceutical precautionary measures suggested by the World Health Organization is to wear mask and maintain minimum physical proximity between the two individuals. The proposed system processes the surveillance video captured through CCTV cameras from college campus, detects the persons from the video and computes the physical proximity between people in the captured spaces. The proposed approach also provides important information about individual person getting in contact with how many other people in the given time duration thereby identifying hotspots in the overall spatial expanse. The module is integrated as a plugin in QGIS which is a contribution to the open source software.
