Intelligent Video Surveillance System Basing On Moving Target Examine

With the improvement of the requirement of family security, how to assure family safety is the urgent requirement at present. Except for the traditional distinct security system, installing the video monitor system in the home will bring the informational safety defense. And video monitor system for family security is designed.Taking a good advantage of the existing PC which installs one or several cheap camera and connects with network in the common family, we can build a practical and cheap family monitor system. That system monitors the scenes in the family. Using real time analysis of moving target for the senses, the system will do the correspondence action.Alarm is the most useful function in the system. And the foundation of alarm is the result of the moving target examine in image sequences. Combining the advantages of the background differencing algorithm and the temporal differencing algorithm, the paper gave an improved algorithm. Not only did it realize the function of alarm, but also assured the accuracy.As an excellent framework of building multimedia information system, the DirectShow technology is the best choice of developing audio and video applications on the Windows. It provides the mature and easy-learned SDK for the developer. DirectShow is a power tool in real time in capturing, encoding and playing audio and video. The family video monitor system uses the DirectShow technology as a framework of implementing the functions such as video capture, image encoder and image detecting. This article discusses the base principle of developing the digital video monitoring system. And it uses the DirectShow Filter to encapsulate to image monitoring module. And it describes how to design and implement the image monitoring module.In a word, the article discusses the video monitor system basing on the method of moving targets examine. Moreover, it probes into the way of how to design by using DirectShow.
