absolute_phase — 3D structured_light op

• Data kinds: image2d × image2d → image2d

• Call: import fringe; fringe.absolute_phase(wrapped, coarse) -> 'np.ndarray' (or ops3d.get("absolute_phase"))

Usage

Turn a wrapped phase into an absolute one by fixing its fringe order from a coarse but absolute phase estimate.
