Multiview video based virtual teleconferencing synthesizing

Building a human-computer interaction environment that supports natural communication and interaction among participator groups is the key issue of virtual teleconferencing system. We introduced a method that uses multiple projection screens to construct semi-immerse virtual environment, which established the correct space relationship of participators, proposed a watersheds based algorithm for stably real time video object extracted from static background and implemented position based multi-view video reconstruction and synthesizing.
