Video Surveillance Oriented Image Quality Assessment System Design

With the rapid development of video image technology,a large number of video surveillance systems have been constructed and been widely used,video images have become the important data resource for social public security and urban management.The quality of video surveillance image is very important.Therefore,it is needed to assess the image quality during the process of system inspection.The traditional assessment of monitoring image is subjective evaluation method,which is time-consuming and inconvenient in practice.And nowadays digital video surveillance system has completely replaced the analog video system,and the objective test method of analog video is not fully suitable for digital video system.At the same time,in the process of surveillance video management,we pay much attention to the engineering construction,while the long-term supervision of the system is always ignored.After the video surveillance related equipment has been in operation for a long time,clearness of surveillance image cannot be guaranteed.Therefore,it is necessary to research the image quality objective evaluation method suiting for video surveillance system,and design an image quality assessment system,which will make assessment more efficient and give technical support to the engineering inspection and system sustainment supervision.
