| Moving object detection and video behavior analysis has become one of the hotspots in modern society. Analysis and hazard identification is also on the foundation of it.Through moving object detection and classification algorithm ,we can dig up more information from the video.We do further research on the foundation of prior research and adopt Pathfinding algorithm , Bayesian estimation to classify the relationship between two people.The system can be used in supermarket ,office and some important place .It also can be used for investigation work.At the same time,the system can help us collect information,can be widely used in market analysis ,can be used to get more commercial value. |
