Appl Intell (Dordr) 2022 Apr 5:1-15. Epub 2022 Apr 5.

Center for Research in Mathematics CIMAT AC, campus Zacatecas, Avenida Lasec, Andador Galileo Galilei, Manzana 3 Lote 7, Parque Quantum, Zacatecas, 98160 Mexico.

With the relaxation of the containment measurements around the globe, monitoring the social distancing in crowded public spaces is of great importance to prevent a new massive wave of COVID-19 infections. Recent works in that matter have limited themselves by assessing social distancing in corridors up to small crowds by detecting each person individually, considering the full body in the image. In this work, we propose a new framework for monitoring the social-distance using end-to-end Deep Learning, to detect crowds violating social-distancing in wide areas, where important occlusions may be present.
