hausdorff_distance — 3D `metrics` op

• Data kinds: points × points → measurement

• Call: import metrics3d; metrics3d.hausdorff_distance(a, b) (or ops3d.get("hausdorff_distance"))

Usage

The symmetric Hausdorff distance = max(max_a min_b, max_b min_a). → scalar. The worst-case discrepancy.

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.
