Abstract

We have proposed an improved regularized phase-tracking (RPT) technique for unwrapping two-dimensional principal phase maps. Simulated annealing (SA) algorithm is applied to RPT technique for finding the global optimum values. Further, the size of the neighborhood selected for plane approximation at each pixel is adjustable according to local noise quantity. In the area of low noise, the size of neighborhood is small to improve processing speed. On the contrary, a neighborhood with large size is selected to enhance the noise-reduced ability in the high-noisy area. Numerical simulation proves that this technique is highly robust to noise and experimental results show the feasibility of this technique.
