Digital image processing algorithms have been developed for phase unwrapping, phase restoration, and phase fitting. During the processing steps a binary mask is used to solve the problem of invalid areas. Experimental results for the strain components at the surface of a simple object demonstrate a...
A temporal phase-unwrapping algorithm has been developed for the analysis of dynamic interference patterns generated with interference-contrast microscopy in micromachined picoliter vials. These vials are etched in silicon dioxide, have a typical depth of 6 mum, and are filled with a liquid sample. ...
The phase unwrapping problem in one dimension can be observed in Figure 12 . The wrapped phase found with the arctangent function is seen in Figure 12a and the unwrapped continuous phase is showed in Figure 12b . Figure 12. Wrapped (a) and unwrapped phase (b). The described p...

Adaptive noise reduction of InSAR images based on a complex-valued MRF model and its application t o phase unwrapping problem We propose a new adaptive noise reduction method for interferometric synthetic aperture radar (InSAR) complex-amplitude images. In the proposed method, we ... AB Suksmono...
the average velocity excluding noisy SAR acquisitions, which are identified using an outlier detection method based on the root mean square of the residual phase. The routine workflow includes three new methods to correct or exclude phase-unwrapping errors for two-dimensional algorithms: (i) the ...

Then phase unwrapping and correction are carried out to obtain the true phase value of the tablet, and the effective refractive index of the tablet is obtained by calculating the phase difference between the tablet and the air. At the same time, the theoretical model of zero porosity ...
It is shown that this solution is consistent with the other phase unwrapping approaches as beat wavelength or Chinese remainder theorem-based solutions, but moreover, it can be understood as a unified representation and solution of the fringe order problem. (C) 2013 Optical Society of America ...
