APPLICATION OF INTEGRAL OPTICAL FLOW FOR ANALYSIS OF CROWD MOVEMENT USING VIDEO SURVEILLANCE SYSTEMS
Abstract
Studying the crowd movement is an important practical task, the solution of which is used in video surveillance systems to prevent emergencies. Generally, a group of people moving at high speed is of more interest than motionless or slow moving people. In this paper, we propose a new method for analyzing the crowd movement based on integral optical flow in a video sequence. We define and calculate several properties of moving crowd including density, motion speed, motion direction and symmetry, in/out index. These properties are useful for further analysis of video scene.
