ParWave: Granularity in Parallel Wavelet Packet Video Coding

摘要

In this work, we discuss different granularities for parallel wavelet packet video coding using block-based motion compensation and the performance of the corresponding MPI implementations on the HLRS Cray T3-E. Two inter-frame based parallelization methods (group-of-picture parallelization and frame-by-frame parallelization) are compared against intra-frame parallelization. We highlight the advantages and drawbacks of all three approaches.
