Abnormal behavior detection in elevator car based on corner kinetic energy model

To avoid fighting,robbery and violence occurred in the elevator car,this paper proposed an abnormal behavior detection model based on corner kinetic energy by analyzing the input video to achieve real-time safety monitoring.Firstly,proposed a method of extracting foreground object by matching the background edge model using Hausdorff distance.Then,detected the corner of object edge to calculate its optical flow,and established the kinetic energy model of the overall object accor-ding to the optical flow velocity vector of the edge corner to detect abnormal behavior.Experimental results show that the method can detect abnormal behavior in the elevator car effectively,and the algorithm is of low computation complexity thus it can alarm real-time.
