edge_points — 3D edges op

• Data kinds: voxel → points

• Call: import edges3d; edges3d.edge_points(edge_mask) -> 'np.ndarray' (or ops3d.get("edge_points"))

Usage

Turn an edge mask into an (M,3) coordinate point set (for downstream chamfer / Hough).

References (sample data, literature)

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

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

Runnable examples (verified samples that actually call this op)

• edges_3d — py -3.11 examples_3d/edges_3d.py
