Title
Low complexity connectivity driven dynamic geometry compression for 3D Tele-Immersion
Abstract
Geometry based 3D Tele-Immersion is a novel emerging media application that involves on the fly reconstructed 3D mesh geometry. To enable real-time communication of such live reconstructed mesh geometry over a bandwidth limited link, fast dynamic geometry compression is needed. However, most tools and methods have been developed for compressing synthetically generated graphics content. These methods achieve good compression rates by exploiting topological and geometric properties that typically do not hold for reconstructed mesh geometry. The live reconstructed dynamic geometry is causal and often non-manifold, open, non-oriented and time-inconsistent. Based on our experience developing a prototype for 3D Teleimmersion based on live reconstructed geometry, we discuss currently available tools. We then present our approach for dynamic compression that better exploits the fact that the 3D geometry is reconstructed and achieve a state of art rate-distortion under stringent real-time constraints.
