MATLAB Code and Example Data for Fast and Accurate Phase Unwrapping of Complex Phase Maps

This MATLAB package provides <b>FAPUX</b> implementation for <b>fast, accurate, and robust phase unwrapping solution</b>, designed to handle <b>challenging phase maps with discontinuities, and intricate spatial structures</b> (e.g., spiral shear phase maps). While it excels in complex scenarios where conventional algorithms often fail, it is <b>equally applicable to smooth and noise-free phase data</b>, making it a versatile tool for a wide range of applications.It is particularly useful in <b>optical metrology, interferometry, SAR/InSAR imaging, and medical diagnostics</b>, where reliable phase recovery is essential.The scripts support the paper <i>“ D.
