Skeletonization¶

Main routines for fast 3d skeletonization.

Note

Supported algorithsm are:

ClearMap.ImageProcessing.Skeletonization.PK12 - parallel 3d 12 sub-iteration thinning algorithm by Palagyi and Kuba [Palagy1999].
RC6 - parallel 3d 6 sub-iteration istmus-based thinning algorithms [Raynal2000].

skeletonize(source, sink=None, points=None, method='PK12i', steps=None, in_place=False, verbose=True, **kwargs)[source]¶

Skeletonize 3d binary arrays.

Arguments

sourcearray or source: Binary image to skeletonize.
sinksink specification: Optional sink.
pointsarray or None: Optional point list of the foreground points in the binary.
methodstr: ‘PK12’ or faster index version ‘PK12i’.
stepsint or None: Number of maximal iteration steps. If None, maximal thinning.
in_placebool: If True, the skeletonization is done directly on the input array.

Returns

skeletonSource: The skeletonized array.
