2D Weighted Phase Unwrapping

Robust and fast 2D weighted phase unwrapping based on Ghiglia and Romero (1994)

In phase retrieval applications, such as interferometry, people are facing the problem of phase being wrapped (i.e. it has value only from -pi to pi). To make the results more useful, one needs to unwrap the phase. This scripts implements the algorithm from Ghiglia and Romero (1994) that uses least-square methods to solve the problem. The algorithm runs relatively quickly and the algorithm is also robust to noise.
