3D tele-immersion (3DTI) has the potential of enabling virtual-reality-like interaction among remote people with real-time 3D video. However, today’s 3DTI systems still suffer from various performance issues, limiting their broader deployment, due to the enormous demand on temporal (computing) and spatial (networking) resources. Past research focused on system-centric approaches for … Read more
