Scalable Video-based Dynamic Mesh Coding

Video-based dynamic mesh compression is being developed for a standard for compressing time-varying mesh data by using existing 2D video codecs. In this paper, we propose a spatial scalable structure for video-based dynamic mesh compression to support scalable applications of the dynamic mesh coding. To support the spatial scalable functionality for geometry, we propose a level of detail based displacement frame packing method that enables decoding up to a certain level. For texture scalable coding, multi-layer texture map is generated from high resolution texture map, and then the scalable high efficiency video coding (SHVC) is employed to remove redundancy between layers. The experimental results demonstrate that our proposed scalable coding method can improve the BD-rate in a 3-layer scalable configuration.
