Recent trends in crowd analysis: A review

Mounir Bendali-Braham, Jonathan Weber, Germain Forestier, Lhassane Idoumghar, Pierre-Alain Muller
2021 Machine Learning with Applications  
In this review, we explore various studies related to crowd analysis. Crowd analysis is commonly broken down into two major branches: crowd statistics and crowd behavior analysis.  ...  When crowd statistics determines the Level Of Service (LoS) of a crowded scene, crowd behavior analysis describes the motion patterns and the activities that are observed in a scene.  ...  Although their method can be used in real-time in a multi-cameras setup, the use of RGBD cameras is not enough widespread to make their algorithm applicable in every situation.  ...
