reflection_symmetry_score — 3D symmetry op

• Data kinds: points → measurement

• Call: import symmetry3d; symmetry3d.reflection_symmetry_score(points, plane_point, plane_normal) (or ops3d.get("reflection_symmetry_score"))

Usage

Reflection-symmetry score = chamfer(mirrored, original) / the median nearest-neighbour spacing (smaller is more symmetric; scale invariant). → float.

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)

• dl_mesh_symmetry — py -3.11 examples_3d/dl_mesh_symmetry.py
