Abstract: Based on the static single-camera surveillance video, this paper proposes a video
analysis based on statistical methods of classroom behavior. Firstly, video sequences are segmentalized
and moving targets are tracked. Then, by tracking the location of the target and monitor status
information for the regional model, four different displacement models are presented. Finally, the
displacement model is used to achieve the number of behavior in or out of the control area. This
method is simple and practical, can not only achieve satisfactory results, but also have
certain robustness. The experimental result shows some practical significance for schoolrelated
departments to understand and grasp the classroom teaching circumstances.

Key words: video surveillance, target tracking, displacement modeling, object counting
