Analysis System And Key Technique Research On Moving Human Activity

Visual analysis of human motion from video sequences has been attached more and more important to computer visions recent few years. Research in this domain involves wide application (including security surveillance, human-computer interface, the details analysis of human movement, etc.).Especially after the event 9.11, security issues have been paid unprecedented attention around the whole world. The Intelligent Security Monitoring System based on computer vision not only completes the safeguard tasks efficiently, but also saves a great deal of human labor and efforts and provides as well as great economic benefits to the society.Focusing on the application of the Intelligent Security Monitoring, this paper designs a relevant human motion analysis system. On the research of the moving objects detection and extraction, combining the Background Subtraction and Temporal difference, this paper resolves the problem that current methods can't obtain the integrated moving human contour. On this condition, using the technology of Template Matching, this paper achieves to automatically analyze the human activity, and then some exceptional human activity can be recognized.
