Abstract
The reconstruction of absolute phase data from its wrapped phase is called Phase Unwrapping (PU). Usually, the absolute phase cannot be extracted from the fringe phase data directly. Ideally, without phase noise, singularity, and aliasing problems, the phase information can be unwrapped easily. However, the phase data are always contaminated by noise and discontinuities, making the PU process becomes more complicated and a suitable PU algorithm is required to address the problems properly. In this paper we are compared phase unwrapping energy minimization approach method at fist and third level pixels configuration.
