BEHAVE: Computer-assisted prescreening of video streams for unusual activities

BEHAVE is funded by the UK's Engineering and Physical Science Research Council (EPSRC) project GR/S98146.


The project will investigate two novel computer-based image analysis processes to prescreen video sequences for abnormal or crime-oriented behaviour. The ultimate goal is to filter out image sequences where uninteresting normal activity is occurring, as well as the much easier sequences where nothing is occurring. The two applications to be investigated are:

  1. Detecting, understanding and discriminating between similar types of interactions, such as two people fighting versus meeting and greeting. For example, are the two people in the green box here fighting?

  2. Analysing crowd scenes, where tracking of individuals is only possible over short time periods, where there might be many hundreds of people simultaneously in view, and where the overall flow of the crowd is more salient than the actions of any individual. The goal is to discriminate between normal behaviour, such as people normally exiting from a football match, and abnormal behaviour, such as when people have to divert around an obstacle (fallen person, fight, etc).

The project started on October 1, 2004 and continues until September 30, 2007.


To address the main scientific questions, the project will research methods for:
