MPEG activities for 3D video coding

In this paper, we introduce the 3D video coding research activities of the moving picture experts group (MPEG), the leading international standardization group for multimedia. Since 2001, MPEG has worked on a number of 3D video coding projects, notably, 3D audio-visual (3DAV), free-viewpoint television (FTV), multi-view video coding (MVC) and 3D video coding (3DVC). Such research works have significantly contributed to the 3D video processing industry. Since multi-view video and depth maps are critical parts of 3D video, the handling techniques of such components have evolved throughout the years. MPEG will continuously develop efficient standards for emerging 3D video applications.
