voxel_iou — 3D `metrics` op

• Data kinds: voxel × voxel → measurement

• Call: import metrics3d; metrics3d.voxel_iou(vol_a, vol_b, iso=0.5) (or ops3d.get("voxel_iou"))

Usage

The IoU (intersection over union) of voxel occupancy. → [0,1]. Volumetric agreement.

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.
