Multi-baseline UKF phase unwrapping algorithm via joint phase slope estimator

Unwrapping highly wrapped phase using Nonlinear Multi Echo phase unwrapping

The unwrapping problem has been a major topic of research for over a decade. A variety of algorithms were suggested, but a correct solution is by no means guaranteed. In addition, many of these techniques are timeconsuming issues. In this work, we propose a simple and fast method, which combines conventional temporal unwrapping with a nonlinear phase model to unwrap highly wrapped Multi Echo da...

Phase-unwrapping algorithm for noisy phase-map processing.

Automated fringe-pattern processing is important in a great number of industrial applications, such as optical data testing and quality control. One of the main problems that arises with these processes is the automated phase unwrapping of the phase map associated with the fringe pattern. Usually the phase map presents problems such as noise, and low-modulation areas. A new phase-unwrapping alg...

PUMA: Phase Unwrapping via MAx flows

Phase unwrapping is the inference of absolute phase from modulo-2π phase. This paper synthetically presents an energy minimization framework for phase unwrapping. The considered objective functions are first-order Markov random fields. We provide an exact energy minimization algorithm, whenever the corresponding clique potentials are convex, namely for the phase unwrapping classical L norm, wit...

Quantitative Phase Imaging using Multi-wavelength Optical Phase Unwrapping

Phase Unwrapping

Phase unwrapping is the reconstruction of the originaltrue phase of a wave from its modulo 2p values. It origi-nates in a variety of applications, such as synthetic aper-ture radar, magnetic resonance imaging, and adaptiveoptics. In this article, the problem of two-dimensionalphase unwrapping is defined and the challenges are ad-dressed. A variety of established approach...
