skeleton_prune3d — 3D medial op

• Data kinds: voxel → voxel

• Call: import medial; medial.skeleton_prune3d(vol, length=1) (or ops3d.get("skeleton_prune3d"))

Usage

Prune the whiskers (short branches) of a 3-D skeleton. Endpoint removal repeated length times = branches of length <= length are removed.

• Operator provenance and references — the sources of the research/methods this op family came from.
