However, human operators cannot concentrate on many monitors for a long time, and carelessness can hardly be avoided. Therefore, our project developed an integrated intelligent digital video surveillance system on a media processor platform. It provides the functionalities stated as follows. First, we developed a smart camera that can automatically detect and track a moving object. The moving object will be maintained in the middle of the image. Second, we implemented an efficient real-time digital video compression module. The space needed for storage or the bandwidth needed for transmission is reduced. Third, we supported automatic video object segmentation and region-of-interest video coding. The portion of the intruder can be remained clearer under limited bandwidth. Fourth, we also realized the network transmission and the video decoder plug-in on the web browser. The compressed data are transmitted through the network, and the users can see the decoded video by installing the plug-in on the web browser at the receiver end. |
