基于社会力的多人异常行为检测

Multi-people Abnormal Behavior Detection Using Social Force

介绍了一种基于社会力的多人异常行为检测方法。在获取视频中多人区域的光流的基础上,计算区域的社会力,然后统计社会力方向的分布,生成社会力方向直方图,并以直方图熵的大小作为异常行为检测的依据。实验证明,该方法能够有效地检测出区域中多人之间的异常行为。

This paper introduces a multi-people abnormal behavior detection method which is based on social force.On the basis of obtaining the optical flow of multi-people area in video,the social force of the area is calculated,then the direction distribution of social force is built,the direction histogram of social force is created,and the value of histogram＇s entropy is used for ab-normal behavior detection.The experiment shows this method can effectively detect abnormal behavior in multi-people area.
