Abstract
A comparative study is made of phase-unwrapping algorithms that adopt either phase gradients or fringe amplitudes as a reliability measure in the selection of an unwrapping path. To compare with the minimum-phase-gradient spanning-tree algorithm, a maximum cross-amplitude spanning-tree algorithm is proposed, which seeks a spanning tree that maximizes overall edge weights given by the crossamplitudes, i.e., the products of the fringe amplitudes of neighboring pixels. Noise immunity of the cross-amplitude spanning-tree algorithm is demonstrated by experiment and computer simulation.
