[0024] The so-called abnormal behavior in the video refers to the appearance of unusual objects or movements in unusual places or times. A successful method of detecting and identifying abnormal behavior first needs to accurately describe the behavior, then establish a corresponding mathematical model, and finally determine whether there is abnormal behavior by calculating the probability distribution of the extracted features in the video sequence. If there is abnormal behavior, an alert message is sent.
[0025] The present invention will be described in detail below
[0026] The intelligent video surveillance system based on behavior recognition is composed of five parts: video acquisition module, video preprocessing module, behavior recognition module based on Bayesian classification method, host computer management platform and alarm module.
[0027] The video capture module is mainly used to obtain digital video sequences, and then convert them into digital video sequences thr...
