Project Title
Optimized bandwidth usage for real-time remote
surveillance system.
Project Goal
The purpose of this project is to develop a real-time
surveillance system, where a camera could be guided remotely, by the
point of gaze of a human observer, while a smart compression algorithm
will be applied to the attended video stream to address the available
transmission bandwidth.
A human observer will attend a location on a monitor
fed by a remote camera. By capturing the human's point of gaze using
an eye-tracking device, the remote camera could be manipulated in order
to turn towards the attended location of the scene. In addition to that
a clever compression algorithm will be used on the transmitted video
stream so that most of the communication bandwidth will be allocated
to high-fidelity transmission of a small region around the viewer's
current point of regard, while peripheral image regions will be highly
degraded and transmitted over little remaining bandwidth.
