topostats.tracing.skeletonize.get_skeleton(image: numpy.typing.NDArray, method: str) → numpy.typing.NDArray[source]#

Skeletonizing masked molecules.

Parameters:

  • image (npt.NDArray) – Image of molecule to be skeletonized.

  • method (str) – Method to use, default is ‘zhang’ other options are ‘lee’, and ‘thin’.

Returns:

Skeletonised version of the image.all($0).

Return type:

npt.NDArray

Notes

This is a thin wrapper to the methods provided by the skimage.morphology module. See also the `examples <https://scikit-image.org/docs/stable/auto_examples/edges/plot_skeleton.html>_
