hough_sphere_3d — 3D `detect` op

• Data kinds: voxel → primitive

• Call: import match3d; match3d.hough_sphere_3d(vol, device='cpu', radii=None, mc=0.0, iso=0.5, subvoxel=True) (or ops3d.get("hough_sphere_3d"))

• GPU: this op has a GPU path (device="cuda")

Usage

Sphere detection (the 3-D lift of the 2-D Hough circle). Votes the centre = p + sgn·r·n for each radius r.

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)

• detect_primitives_3d — py -3.11 examples_3d/detect_primitives_3d.py

Ops the type connects to (they accept `primitive` as input)
