A New Fast Quality-Guided Flood-Fill Phase Unwrapping Algorithm

Abstract

When unwrapping a phase of a complex wrapped phase map, there are usually phase jumps and time-consuming. The quality-guided flood-fill unwrapping phase algorithm is the most common kind of unwrapping algorithm, and the unwrapping effect is better than others, but it is spend too much time to real-time reconstruction. On the basis of quality-guided flood-fill phase unwrapping algorithm, we have improved the algorithm speed by optimizing path. This article compares the unwrapping effect and the unwrapping time of various common unwrapping methods through experiments. The experimental results show that our proposed approach has good performance.
