Greedily merges the most similar pair of nodes until no edges lower than `thresh` remain. Parameters ---------- labels : ndarray The array of labels. rag : RAG The Region Adjacency Graph. thresh : float Regions connected by an edge with weight smaller than `thresh` are merged. rag_copy : bool If set, the RAG copied before modifying. in_place_merge : bool If set, the nodes are merged in place. Otherwise, a new node is created for each merge.. merge_func : callable This function is called before merging two nodes. For the RAG `graph` while merging `src` and `dst`, it is called as follows ``merge_func(graph, src, dst)``. weight_func : callable The function to compute the new weights of the nodes adjacent to the merged node. This is directly supplied as the argument `weight_func` to `merge_nodes`. Returns ------- out : ndarray The new labeled array.
