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 technical optimization, without taking human users into the loop. We argue that human factors (including user

... erences, semantics, limitations, etc.) are an important and integral part of the cyber-physical 3DTI systems, and should not be neglected. This thesis proposes a novel, comprehensive, human-centric framework for improving the qualities of 3DTI throughout its video function pipeline. We make To Xiao & Sicheng iii
