wrapped_phase — 3D structured_light op

• Data kinds: images → image2d

• Call: import fringe; fringe.wrapped_phase(images) -> 'np.ndarray' (or ops3d.get("wrapped_phase"))

Usage

Compute the wrapped phase (−π, π] from an N-step phase-shifted fringe image series.

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.
