VDE-Net: a two-stage deep learning method for phase unwrapping.
Optics Express, 2022 Phase unwrapping is a critical step to obtaining a continuous phase distribution in optical phase measurements and coherent imaging techniques. Traditional phase-unwrapping methods are generally low performance due to significant noise or undersampling ...

Generalized phase unwrapping method that avoids jump errors for fringe projection profilometry.
Optics Express, 2021 Jump errors easily occur on the discontinuity of the wrapped phase because of the misalignment between wrapped phase and fringe order in fringe projection profilometry (FPP).
