vol_reduce_domain — 3D domain op

• Data kinds: voxel × voxel → voxel

• Call: import volops; volops.vol_reduce_domain(vol, domain) (or ops3d.get("vol_reduce_domain"))

Usage

Restrict a volume to a *domain* mask (HALCON `reduce_domain`, voxel-wise).

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)

• roi_domain_boundary — py -3.11 examples_3d/roi_domain_boundary.py

Ops the type connects to (they accept voxel as input)
