In this paper we present a 3D scene representation with standardized components to be used in interactive applications. For this representation we also show efficient coding of 3D geometry and textures as well as a 3D reconstruction system for creating 3D video objects (3DVOs). Similar to computer graphics objects, 3DVOs provide functionalities, like free scene navigation and animation. In contrast,...
This paper presents a study on video plus depth compression using available MPEG standards and its optimization for mobile 3D services. Video plus depth enables 3D television, but as mobile services are subject to various limitations, including bandwidth, memory, and processing power, efficient compression as well as low complexity view synthesis is required. Two MPEG coding standards are applicable...
Different methods for coding of stereo video content for mobile 3DTV are examined and compared. These methods are H.264/MPEG-4 AVC simulcast transmission, H.264/MPEG-4 AVC Stereo SEI message, mixed resolution coding, and video plus depth coding using MPEG-C Part 3. The first two methods are based on a full left and right video (V+V) representation, the third method uses a full and a subsampled view...
This paper presents a new compression technique for 3D dynamic meshes, referred to as FAMC - Frame-based Animated Mesh Compression, recently promoted within the MPEG-4 standard as Amen-dement 2 of part 16 (AFX -Animation Framework extension). The FAMC approach combines a model-based motion-compensation strategy with transform/predictive coding of residual errors. First, a skinning motion-compensation...
