6.14.1. scikits.learn.feature_extraction.image.img_to_graph¶
- scikits.learn.feature_extraction.image.img_to_graph(img, mask=None, return_as=<class 'scipy.sparse.coo.coo_matrix'>, dtype=None)¶
Create a graph of the pixel-to-pixel connections with the gradient of the image as a the edge value.
Parameters : img: ndarray, 2D or 3D :
2D or 3D image
mask : ndarray of booleans, optional
An optional mask of the image, to consider only part of the pixels.
return_as: np.ndarray or a sparse matrix class, optional :
The class to use to build the returned adjacency matrix.
dtype: None or dtype, optional :
The data of the returned sparse matrix. By default it is the dtype of img
