Memory-efficient watershed delineation using OpenMP (ongoing)
My ongoing parallel computing research introduces a memory-efficient watershed delineation algorithm using OpenMP. These figures compare the performance of the new algorithm and its variants (mefshed*) with that of a fast CUDA-based benchmark algorithm published earlier this year (wdg).
