Abstract
Summary form only given. We implemented parallel algorithms for vector quantization (VQ) compression on a shared-memory parallel environment and evaluated the effectiveness of the parallel algorithms. On such a system, we evaluate two parallel algorithms for the codebook generation of the VQ compression: parallel LBG and parallel tPNN and find that the parallel tPNN is superior in terms of space complexity, whereas the parallel LBG is superior in terms of time complexity and parallelism
