Phase-unwrapping algorithm by a rounding-least-squares approach
What's it about?
Phase-unwrapping is an essential procedure of fringe analysis routines. In this paper, an efficient phase-unwrapping algorithm, which operates over the gradient of the phase jumps by a robust and noniterative scheme, is proposed. Since the proposed algorithm is fast and user-free, it could be used in automatic real-time fringe-projection applications.
