The Development Of Video Surveillance System And The Research On Restoration Of Motion-blurred Image

The video surveillance system is a very comprehensive system, which is an important part of security fence system. Because of its convenience, directness and abundance in information, it is very popular in many fields. With the development of computer technologies, network technologies, image-processing technologies and transmission technologies, the development of video surveillance system shows great potential. Thus, there are not only theory values but also great market values in the research of this system. This thesis focuses on the research of video surveillance system and the algorithms on how to restore motion-blurred image.Firstly, the history and tendency of video surveillance system are introduced briefly, some typical devices and structures are summarized and their advantages and disadvantages are presented. Then, the developing processing of large-scale video switcher, local surveillance unit and camera decoder are discussed in detail, especially the structure design, functions design, important circuits, developing difficulties and improvement.In addition, the cause of motion-blurred image in video surveillance system is analyzed. Then, the algorithms on how to restore image are presented. The emulation result shows that those algorithms are effective.
