sklearn.feature_extraction.image.img_to_graph(img, mask=None, return_as=<class ‘scipy.sparse.coo.coo_matrix’>, dtype=None)
Graph of the pixel-to-pixel gradient connections
Edges are weighted with the gradient values.

For scikit-learn versions 0.14.1 and prior, return_as=np.ndarray was handled by returning a dense np.matrix instance. Going forward, np.ndarray returns an np.ndarray, as expected.
For compatibility, user code relying on this method should wrap its calls in
np.asarray to avoid type issues.
