Recognition of Abnormal Human Behavior using Kinect Case Study: Tehran Metro Station

Objectives: The ability of detecting people and understanding their behaviors for recognition or detection of special event has attracted significant research interest in recent years. Methods: The main purpose of this study focuses on abnormal human behavior detection by using Microsoft’s Kinect camera. By utilizing Kinect, the system tracks all persons in Metro station and calculates their position relations, which provide a more effective way to analyze human’s behavior. Results: It first applies Kinect technology of Microsoft in the field of intelligent monitoring. By taking use of the depth information, the system recognizes unusual behavior and by face detection and analysis, the system of face-hiding behavior. The time people spend in Metro station is recorded and spending too much time is also regarded as an abnormal behavior. Applications: Experiments show that the system is very robust for abnormal behavior recognition and provides a new way for preventing Metro station crimes.
