vol_rle_union — 3D rle_region op

• Data kinds: rle_region × rle_region → rle_region

• Call: import volregion; volregion.vol_rle_union(a, b) (or ops3d.get("vol_rle_union"))

Usage

Union of two RLE regions, computed on the runs (no decode). Cost scales

• 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)

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