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...
متن کاملVery loopy belief propagation for unwrapping phase images
Since the discovery that the best error-correcting decoding algorithm can be viewed as belief propagation in a cycle-bound graph, researchers have been trying to determine under what circumstances "loopy belief propagation" is effective for probabilistic inference. Despite several theoretical advances in our understanding of loopy belief propagation, to our knowledge, the only problem that has ...
متن کاملHybrid random walk-linear discriminant analysis method for unwrapping quantitative phase microscopy images of biological samples.
Standard algorithms for phase unwrapping often fail for interferometric quantitative phase imaging (QPI) of biological samples due to the variable morphology of these samples and the requirement to image at low light intensities to avoid phototoxicity. We describe a new algorithm combining random walk-based image segmentation with linear discriminant analysis (LDA)-based feature detection, usin...
متن کاملImproved phase-unwrapping method using geometric constraints
Conventional dual-frequency fringe projection algorithm often suffers from phase unwrapping failure when the frequency ratio between the high frequency and the low one is too large. Zhang et.al. proposed an enhanced two-frequency phase-shifting method to use geometric constraints of digital fringe projection(DFP) to reduce the noise impact due to the large frequency ratio. However, this method ...
متن کاملPhase unwrapping method based on stochastic relaxation
We propose a new method for phase unwrapping based on Stochastic Relaxation. A cost functional is introduced as a measure of the smoothness of the unwrapped phase eld. Hence the problem of reconstructing the unwrapped phase eld can be formulated as a minimization problem for the integer deviations between the measured and the unknown neighboring pixel diierences of the true phase, with the cons...
