內建智慧型自動追蹤攝影機之數位視訊監控系統

Video surveillance systems assist humans
by providing an extended perception and
reasoning capability about situations of interest in
the monitored environments. 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.
