Abandoned And Stolen Object Detection Based On Video Analysis

With the rapid growth of world economy and the strengthening of comprehensive national strength, demands for security system of electric power, transportation, bank, security and military facilities and other areas grow with each passing day. At the same time, the requirement become higher and higher. In a word, video surveillance has been widely used in various aspects of life. In order to analyse, track, discriminate monitoring objects in real time, immediately prompt or alarm when an abnormal event occurs, and provide support to related departments to make timely decisions and right action, the intelligent of video surveillance is particularly important. With the development of computer performance and the improvement of the machine vision research, the intelligent monitoring system based on video analysis emerges at the right moment.On the basis that after analysing the demand of abandoned and stolen object detection function in intelligent monitoring system, this topic has carried on the analysis and research of the corresponding algorithm about the common processing steps of video analysis, including target detection, target tracking, and target analysis.In view of the shadow problems caused by light factors, through the use of background model and shadow model based on mixture Gaussian, the topic removes the shadow successfully and extracts the foreground object accurately; In view of the situation that occasional checking failures often occur in actual scene due to occlusion, through the tracking method based on region matching, the topic deals with the problem finally; In view of the situation that pedestrians are mistakenly identified as abandoned objects or stolen objects due to they stay for a long time in the scene, through people detection, the topic removes the interfere to detection; At last, through the characteristics of abandoned object and stolen object in time domain and space domain of specific areas, the topic distinguishes each other effectively.At the same time, this topic designs and realizes the soft system of abandoned and stolen detection based on video analysis by programming. On the basis of demand analysis of system, this topic designs the system interface by using the development way that VC++combined with OpenCV and realizes the functions of result show, parameter adjustment and control operation.
