Real-time compression of depth streams through meshification and valence-based encoding

Free viewpoint telepresence is currently an active and very interesting field of research. Its focus is reproducing in real-time a remote subject (or environment) in a way it can be rendered from an arbitrary point-of-view. This paper presents a novel approach to real-time reconstruction and transmission of a high-quality 3D model of the subject/environment based on the meshification of the depth map produced by a range camera system (i.e. time-of-flight, Kinect). The generated mesh is compressed through a variant of the state-of-the-art single-rate mesh compression algorithm, ready to be transmitted over the network towards the rendering location in a fast and efficient way.
