Abstract
This paper concerns the design of a system supporting teleconferencing applications. This system aims at creating an immersive environment by compositing a synthetic background with the reconstructed images of remote participants. It also presents natural scenes by employing viewer tracking and rendering images from the vantage point of the viewer. Processing requirements are met by exploiting existing networks of workstations by means of a quality of service based resource management scheme. This approach offers advantages with respect to the application itself (teleconferencing) and resource requirements. By restricting the transmitted images to the participants only, the required bandwidth becomes much smaller and video quality can be achieved. The employed resource management scheme limits computational resources to general purpose workstations. On the other hand, a synthetic background that matches the real meeting room can be easily designed, giving the impression of a virtual meeting room as an extension of the real one. In this way, remote conference sessions that resemble real life meetings can be held.
