Title The Detection and Analysis Technology of Abnormal Retentate On the Pavement
Abstract In recent years, the intelligent monitoring system has been widely used in all fields. It adopts the technology of image processing, pattern recognition and computer vision. Through the intelligent video analysis module, it use the aid of the computer's powerful data processing ability to filter out the useless information in video, and analyze the useful information. It can quickly judge the abnormal conditions in monitoring system, and alarm or trigger other actions with the fastest and best way.
This thesis has done some research on the research direction of the monitoring facilities, and found the retentate parts have great research value . The experiment system is mainly based on the frame difference method and background difference method. The system first detect different scenarios on the video, and use different algorithms to detect the target object according to different scenarios. In this way, we can lower the false alarm rate, improve the accuracy of relative left objects detection.
