TiPS: A lightweight Tele-immersive photograph system

This paper presents a lightweight Tele-immersive photograph system named TiPS. TiPS allows remote users to take a photo as a souvenir in a virtual space with natural social behavior, through adaptively merging two participants of remote video interaction into the same shared background. We address two key technologies in this paper, first, we propose an adaptive multi-cue decision fusion algorithm for accurate and robust foreground segmentation of live video. Second, we present a user behavioral intention driven video composition algorithm, aiming at obtaining life-like photographs in real time. Experimental results show TiPS achieves high performance in both foreground segmentation and video composition, which well satisfies remote users´ requirement of taking photos together.
