WebThe PlanarCut-v1.0.2 library computes max-flow/min-s-t-cut on planar graphs. It implements an efficient algorithm, which has almost linear running time. The library also provides for several easy-to-use interfaces in order to define planar graphs that are common in computer vision applications. The code was implemented by Eno Töppe and … Web对 Region Adjacency Graph 执行 Normalized Graph cut。 给定图像的标签及其相似性 RAG,递归地对其执行 2-way normalized cut。 属于不能被进一步切割的子图的所有节点在输出中被分配一个唯一的标签。
