We develop a volumetric video system which supports interactive browsing of compressed time-varying volumetric features (significant isosurfaces and interval volumes). Since the size of even one volumetric frame in a time-varying 3D data set is very large, transmission and on-line reconstruction are the main bottlenecks for interactive remote visualization of time-varying volume and surface data. We describe a compression scheme for encoding time-varying volumetric features in a unified way, which allows for on-line reconstruction and rendering. To increase the run-time decompression speed and compression ratio, we decompose the volume into small blocks and encode only the significant blocks that contribute to the isosurfaces and interval volumes. The results show that our compression scheme achieves high compression ratio with fast reconstruction, which is effective for client-side rendering of time-varying volumetric features.

用于交互式播放的体积视频压缩。


我们开发了一种体积视频系统，支持压缩时变体积特征（重要的等值面和间隔体积）的交互式浏览。由于时变3D数据集中即使是一个体积帧的大小也非常大，传输和在线重建是时变体积和表面数据交互式远程可视化的主要瓶颈。我们描述了一种以统一方式编码时变体积特征的压缩方案，该方案允许在线重建和渲染。为了提高运行时解压缩速度和压缩比，我们将体积分解为小块，并仅对对等值面和区间体积有贡献的重要块进行编码。结果表明，我们的压缩方案实现了高压缩比和快速重建，这对于时变体积特征的客户端渲染是有效的。
