elastic_deform — 3D augment op

• Data kinds: points → points

• Call: import pcl_augment; pcl_augment.elastic_deform(points, sigma: 'float', alpha: 'float', seed: 'int' = 0) -> 'np.ndarray' (or ops3d.get("elastic_deform"))

Usage

Elastic deformation by a smooth random displacement field (correlation length `sigma, RMS amplitude alpha`).

• 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)

• sensor_seg — py -3.11 examples_3d/sensor_seg.py
