Signature

   class     RAG (    label_image    =  None   ,    connectivity    =  1   ,    data    =  None   ,   ** attr      )

The Region Adjacency Graph (RAG) of an image, subclasses networkx.Graph.

label_image : array of int: An initial segmentation, with each region labeled as a different integer. Every unique value in label_image will correspond to a node in the graph.
connectivity : int, in range [1, `label_image.ndim`], optional: The connectivity between pixels in label_image. For a 2D image, a connectivity of 1 corresponds to immediate neighbors up, down, left, and right, while a connectivity of 2 also includes diagonal neighbors. See scipy.ndimage.generate_binary_structure.
data : :obj:`networkx.Graph` specification, optional: Initial or additional edges to pass to networkx.Graph constructor. Valid edge specifications include edge list (list of tuples), NumPy arrays, and SciPy sparse matrices.
**attr : Any, optional: Additional attributes to add to the graph.
