Phase Imaging : Unwrapping and Denoising with Diversity and Multi-resolution

Abstract

Many imaging techniques, e.g., interferometric synthetic aperture radar (InSAR), and magnetic resonance imaging (MRI), yield phase images. In these, generally, each pixel retrieves the phase up to a modulo-2π rad ambiguity, i.e., the phase wrapped around the principal interval [−π π[. Phase unwrapping (PU) is, then, a crucial operation to obtain absolute… (More)
