This webpage contains two video files that show the results of the developed system on the PETS2009 benchmark data [1]. The output of the system is given as a graphic overlay, i.e. adding arrows and colors to the original video (images) in order to show crowds and their movement.

 

       Video for scenario 1: Crowd merging. This scenario contains a densely grouped crowd and a single person joining it.

 

       Video for scenario 2: Crowd splitting. In this scenario, a single crowd is moving diagonally. At a point it splits up into 3 different crowds.
