Parallel algorithm of region growing based on multi-level queue
一种基于多级队列的并行区域生长算法

Region growing is one of classical image segmentation methods. In order to satisfy the real-time request of image segmentation, a parallel algorithm of region growing based on multi-level queue was proposed. The algorithm adopted multi-level queue to deposit seed pixels for growing. Boundary seed pixels were grown preferentially, so as the seed pixels beyond boundary were generated early. Therefore, waiting time of neighbors was reduced. Experiments show that compared with general algorithm based on single queue, speed-up ratio of the algorithm can be promoted significantly and its sealability is better.
