Fast and robust three-dimensional best path phase unwrapping algorithm.
What we believe to be a novel three-dimensional (3D) phase unwrapping algorithm is proposed to unwrap 3D wrapped-phase volumes. It depends on a quality map to unwrap the most reliable voxels first and the least reliable voxels last. The technique follows a discrete unwrapping path to perform the unwrapping process. The performance of this technique was tested on both simulated and real wrapped-...
متن کاملFast and accurate phase unwrapping
More and more speech technology and signal processing applications make use of the phase information. A proper estimation and representation of the phase goes inextricably along with a correct phase unwrapping, which refers to the problem of finding the instance of the phase function chosen to ensure continuity. This paper proposes a new technique of phase unwrapping which is based on two mathe...
متن کاملPhase-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...
متن کاملA New Algorithm of Phase Unwrapping
Phase unwrapping is one of important task in synthesizes aperture radar (SAR) interferometric measurement data processing procedure. Accuracy of it will directly affects precision of the interferometric measurement result. Through the experimental study, this paper analyzes principle and the characteristic of two kind of main current phases unwrapping algorithm, then conbines respective merit a...
متن کاملA region-growing algorithm for InSAR phase unwrapping
This paper describes a new region-growing algorithm for interferometric synthetic aperture radar (SAR) phase unwrapping. The algorithm is designed to handle noisy interferograms and based on the following principles. 1) Unwrapping is carried out on the perimeter of “growth regions,” and these regions are allowed to grow with consistency checking. 2) Phase information from neighboring pixels is ...
