Phase unwrapping: Project
ثبت نشده
چکیده
There are many medical, military and industrial digital image processing applications which as part of their fundamental operation depend upon the extraction of a phase signal from their input image. Examples of such applications are magnetic resonance imaging (MRI), synthetic aperture radar (SAR), fringe pattern analysis, tomography and spectroscopy. These systems use modern and mature algorithms to extract the phase signal. However the phase is returned in a form that suffers from 2-pi phase jumps due to the use of the mathematical arctangent function, which produces an inherently wrapped output. This wrapped phase is unusable until the phase discontinuities are removed and this is achieved practically by employing a phase unwrapping algorithm.

InSAR Phase Unwrapping by Transforming Sparce Data into a Regular Space
Phase unwrapping is one of the most important parts of InSAR techniques. In order to estimate the grand surface displacements, interferomtric phases modulated between 0 to 2π must be unwrapped. Based on the use of either the conventional method or persistent scatterer (PS), phases will be spread both regularly and irregularly. The phases of PSs can be unwrapped by reducing phases into a regular...
