ABSTRACT

This paper describes a compression scheme for volumetric video data(3D space X 1D time) where each frame of the volume is decompressed and rendered in real-time. Since even one frame size of volume is very large, run-time decompression can be a bottleneck for real-time playback of time-varying volume data. To increase the run-time decompression speed and compression ratio, we decompose the volume into small blocks and only update significantly changing blocks. The results show that our compression scheme compromises decompression speed and image quality well enough for interactive time-varying visualization.
