detect_reflection_symmetry — 3D symmetry op

• Data kinds: points → primitive

• Call: import symmetry3d; symmetry3d.detect_reflection_symmetry(points) (or ops3d.get("detect_reflection_symmetry"))

Usage

Choose the best mirror-symmetry plane among candidates whose normals are the PCA principal axes (through the centroid).

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.
