Abstract
In this paper, we propose a robust phase unwrapping algorithm that can be applied to optic interferometry based on combing the theory of residues and local phase information to mask out the discontinuous regions in the unwrapping. Unlike previous methods, which require subjective appraisal to determine the threshold value of the second differences in a locally unwrapped phase empirically, this technique sets the threshold value in a straightforward way. The technique aims to minimize the loss of phase information produced by erroneous distinguished pixels, and simplifies the unwrapping process. Experimental results on complex discontinuous objects are presented to illustrate the validity of this technique.
