decode_fringe — 3D structured_light op

Data kinds: imagesdepth

Call: import fringe; fringe.decode_fringe(phase_shift_images, ref_phase=None, k=1.0, mask=None, min_modulation=None) -> 'np.ndarray' (or ops3d.get("decode_fringe"))

Usage

Decode a phase-shift image series in one go: wrapped → unwrap → (subtract the reference to get) height.

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.
