vol_local_maxima — 3D feature op

• Data kinds: voxel → points

• Call: import volops; volops.vol_local_maxima(vol, min_distance, threshold=None) (or ops3d.get("vol_local_maxima"))

Usage

3-D local-maxima (peak) detection.

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)

• molecule_atom_count — py -3.11 examples_3d/molecule_atom_count.py

• vessel_metrology — py -3.11 examples_3d/vessel_metrology.py
