Detecting inexplicable behaviour

H. Dee, D. Hogg
2004 Procedings of the British Machine Vision Conference 2004  
This paper presents a novel approach to the detection of unusual or interesting events in videos involving certain types of intentional behaviour, such as pedestrian scenes.  ...  The advantages of such an approach are multiple: it handles the presence of movable obstacles (for example, parked cars) with ease; trajectories which have never before been presented to the system can  ...  This makes use of adaptive colour models such as those in [8] for both foreground and background, and also incorporates a shape model for vehicle tracking.  ...

Recent trends in crowd analysis: A review

Mounir Bendali-Braham, Jonathan Weber, Germain Forestier, Lhassane Idoumghar, Pierre-Alain Muller
2021 Machine Learning with Applications  
Fortunately, more and more important smart cities are adopting the concept of intelligent surveillance systems.  ...  One of the hottest topics of crowd analysis is anomaly detection. Although a unanimous definition of anomaly has not yet been met, each of crowd analysis subtopics can be subjected to abnormality.  ...  The use of this kind of combination is found in tracking for video-surveillance applications.  ...
