| Abstract: | Considering the problems(complicated computation and huge data) of SEBVHOS(surface extraction from binary volumes with high-order smoothness),we propose a parallel algorithm to accelerate the SEBVHOS execution.Firstly,SEBVHOS is parallelized.Secondly,optimization techniques are applied to improve performance of the algorithm.Meanwhile,matrix compression is applied to improve performance of memory space.Experiments show that the average speed-up ratio achieves 1.87 in a dual-core system. |
