match_logpolar_z — 3D `match_pose` op

• Data kinds: voxel × voxel → rot_scale

• Call: import match3d; match3d.match_logpolar_z(a, b, device='cpu', project='mip', nt=360, nr=192) (or ops3d.get("match_logpolar_z"))

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

Usage

Recover rotation about z and isotropic scale by log-polar × phase correlation (Fourier-Mellin).

• 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 `rot_scale` as input)
