Abstract: Video surveillance is very essential as threat and crime increases. In this project, a method is proposed in which the behaviour of crowd is detected without individual tracking of objects in a frame. This method is based on the motion intensity of the crowd which can be determined by accumulating all optical flow vectors of a frame. The abnormal crowd activity can then be detected by setting up a threshold to detect any sudden change in motion intensity.
