TLDR
This work addresses the application of computer vision to semi-immersive teleconferencing, and presents a prototype vision system synthesising a physically plausible video of a speaker to be displayed at a remote conferencing station.Abstract:
We address the application of computer vision to semi-immersive teleconferencing, and present a prototype vision system synthesising a physically plausible video of a speaker to be displayed at a remote conferencing station. The main system components are a hierarchical, efficient large-baseline disparity estimation and a view synthesis module. We illustrate and discuss some results with a real-speaker sequence. We regard the development of such a system in the domain of advanced teleconferencing as the main contribution of this work.read more

Dense wide-baseline disparities from conventional stereo for immersive videoconferencing
Spela Ivekovic,Emanuele Trucco +1 more
TL;DR: An algorithm creating consistent, dense disparity maps from incomplete disparity data generated by a conventional stereo system used in a wide-baseline configuration and performs spline-based disparity interpolation within nonoverlapping regions are defined by discontinuity boundaries identified in the incomplete disparity map.
