Abstract

In recent years, along with the equipment for crime prevention to spread, crime prevention awareness of suspicious behavior called “shoplifting” is increasing. But when you have suffered from shoplifting, it is difficult to identify the perpetrator with only the video of security camera. Therefore, we detect a shoplifting behavior as suspicious behavior from the video of the camera, and it is necessary to consider a method of identifying where the person is in the moving. In this paper, we focus on the movement of the hand with the item, shoplifting operation as a detection object, we consider the method of a suspicious behavior detection based on the characteristic of motion of the hand movements when holding items.
