适用于大型网格图的最大流最小割算法，适合初学者-The regionpushrelabel-v1.03 library computes max-flow/min-cut on huge N-dimensional grid-graphs in graphics, vision, and medical imaging. The C++ implementation is designed specifically for multi-core systems and graphs larger than available memory. Besides nearest-neighbour graphs, the library also supports more complex regular structures to speed up things like QPBO, cell complexes, and Ishikawa-like constructions. The public implementation was developed by Sameh Khamis who is now at the University of Maryland.
