register_spin — 3D `feature_register` op

• Data kinds: points × points → pose

• Call: import feat_spin; feat_spin.register_spin(src, dst, device='cpu', n_keypoints=220, normal_k=18, support_radius=None, n_alpha=16, n_beta=16, support_angle_deg=60.0, lowe_ratio=0.85, ransac_iters=4000, inlier_thr=None, min_inliers=8, seed=0) (or ops3d.get("register_spin"))

Usage

Sparse-feature rigid alignment without an initial guess, using Spin Image descriptors and RANSAC.

• 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.
