moments_central(image, center=None, order=3, **kwargs)
The center coordinates (cr, cc) can be calculated from the raw moments as: { M[1, 0] / M[0, 0]
, M[0, 1] / M[0, 0]
}.
Note that central moments are translation invariant but not scale and rotation invariant.
Rasterized shape as image.
Coordinates of the image centroid. This will be computed if it is not provided.
The maximum order of moments computed.
Central image moments.
Calculate all central image moments up to a certain order.
>>> image = np.zeros((20, 20), dtype=np.double)See :
... image[13:17, 13:17] = 1
... M = moments(image)
... centroid = (M[1, 0] / M[0, 0], M[0, 1] / M[0, 0])
... moments_central(image, centroid) array([[16., 0., 20., 0.], [ 0., 0., 0., 0.], [20., 0., 25., 0.], [ 0., 0., 0., 0.]])

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
