“…Different techniques are used for that purpose, e.g. stereo [KNR95,CSS02], volume carving [KS98], point-based representation and rendering [LWG04,WWCG07], photo-consistency, like voxel coloring [SD97] and its successor photo-hull [YWB03,LMS04b]. The advent of depth video cameras [Ins,Via,Can] open new horizons for novel view synthesis.…”

“…Studies on modern multi-party telepresence systems emerged in the mid-1990s from research in computer graphics and virtual reality. Early systems include CAVE and ImmersaDesk [4] from the University of Illinois at Chicago, and Virtualized Reality from Carnegie Mellon University [5]. Other notable telepresence systems include Virtual Auditorium [6], Virtue [7], Digital Amphitheater [8], and Coliseum [9].…”

Abstract-Telepresence or tele-immersion technologies allow people to attend a shared meeting without being physically present in the same location. Commercial telepresence solutions available in the market today have significant drawbacks -they are very expensive, and confine people to the area covered by stationary cameras. In this paper, we present a mobile tele-immersion platform that addresses these issues by using robots with embedded cameras. In our system, the users can move around freely because robots autonomously adjust their locations. We provide a geometric definition of what it means to get a good view of the user, and present control algorithms to maintain a good view. The algorithms are validated both in simulation and in real experiments.

“…The methods rely heavily on carefully constructed and expensive setup and require special scene arrangement since they are based on scene/object segmentation [1,5,8,17]. Würmlin et al [17] propose dynamic 3D point samples for streaming 3D video.…”

We propose a multiview tracking method for rigid objects. Assuming that a part of the object is visible in at least two cameras, a partial 3D model is reconstructed in terms of a collection of small 3D planar patches of arbitrary topology. The 3D representation, recovered fully automatically, allows to formulate tracking as gradient minimization in pose (translation, rotation) space. As the object moves, the 3D model is incrementally updated. A virtuous circle emerges: tracking enables composition of the partial 3D model; the 3D model facilitates and robustifies the multiview tracking.We demonstrate experimentally that the interleaved track-and-reconstruct approach successfully tracks a 360 degrees turn-around and a wide range of motions. Monocular tracking is also possible after the model is constructed. Using more cameras, however, significantly increases stability in critical poses and moves. We demonstrate how to exploit the 3D model to increases stability in the presence of uneven and/or changing illumination.
