sato(image, sigmas=range(1, 10, 2), black_ridges=True, mode=None, cval=0)
This filter can be used to detect continuous ridges, e.g. tubes, wrinkles, rivers. It can be used to calculate the fraction of the whole image containing such objects.
Defined only for 2-D and 3-D images. Calculates the eigenvectors of the Hessian to compute the similarity of an image region to tubes, according to the method described in .
Array with input image data.
Sigmas used as scales of filter.
When True (the default), the filter detects black ridges; when False, it detects white ridges.
How to handle values outside the image borders.
Used in conjunction with mode 'constant', the value outside the image boundaries.
Filtered image (maximum of pixels across all scales).
Filter an image with the Sato tubeness filter.

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
