Comparison of phase-distribution results obtained using five phase-unwrapping algorithms on three-frame transient interferometric images: Columns 1, 2, and 3 correspond to phase reconstruction results for frames 1, 2, and 3, respectively; Rows (a), (b), (c), (d), and (e) show the unfolded results from different algorithms: (a1), (a2), (a3) represent the Goldstein algorithm; (b1), (b2), (b3) represent the TIE algorithm; (c1), (c2), (c3) represent the N-F algorithm; (d1), (d2), (d3) represent the SRNCP algorithm; (e1), (e2), (e3) represent the improved algorithm.
