Abstract:With the rapid development of national economy, people now have higher requirements for the quality of life. The pace of life is faster and faster and the pressure of work today is larger and larger. people have a strong desire to live a stable and comfortable live, which greatly promoted the development of intelligent community. As there are some disadvantage on the traditional video surveillance system, such as single function, large storage space occupation, running low efficiency. To meet the market requirements, enhance product competitiveness, it's necessary to intelligently extract the original video, to achieve intelligent video surveillance by the powerful computer processing ability.

    First of all ,this paper introduces the related content of image preprocessing and moving object detecting key technology, analyzes the target motion detection algorithm is proposed.On these bases, this paper, in view of the moving object intelligent monitoring, Using MATLAB software to finish the experiment.Puts out the fast detection algorithm of moving object for video sequence of still background, conduct the target detection for each frame of the lengthy building channel computer monitor video files of 5 hours, then make it into a refined , accurate and continuous situation specifically video file of 2 hours .

Key words：Intelligent Extraction ; video analysis ; moving target detection ; MATLAB

　　　基于背景差分析方法的视频监控系统是结合计算机技术、数字图像处理技术、多媒体技术和工业电视技术的综合应用模式，具有性能优越，操作方便、对监控状态判断准确等的特点。在日常生活许多环境下能发挥其作用。并且越来越被社会所接受。如:智能楼宇视频分析监控、智能交通系统、重要地区进出口监控系统等。它的使用将会减少日常生活中的监控压力，为出现意外提供有效的证据，促进了生产和工作的效率。给社会带来了直接的经济效益，是未来的一种理想的监控模式。
