SURE-Fuse WFF: A Multi-Resolution Windowed Fourier Analysis for Interferometric Phase Denoising

Interferometric phase (InPhase) images, acquired by phase imaging systems, often suffer from two major degradations: 1) phase wrapping, caused by the sinusoidal 2\pi -periodic sensing mechanism, and 2) noise, introduced by the acquisition process or the system. This work focuses on InPhase denoisin...
