match_phase_3d — 3D match_pose op

• Data kinds: voxel × voxel → shift

• Call: import match3d; match3d.match_phase_3d(a, b, device='cpu') (or ops3d.get("match_phase_3d"))

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

Usage

3-D phase correlation (FFT). Returns the integer shift (dz, dy, dx) that aligns b to a.

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)

• shape_desc_pose — py -3.11 examples_3d/shape_desc_pose.py

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