Phase Unwrapping Algorithm Based on Relative Distance Guidance
一种相对距离导向的相位展开算法

A new phase unwrapping algorithm based on relative distance guidance was presented.According to the features between two neighboring pixels,the relative distance of two neighboring pixels was defined on complex plane,which composed the relative distance tree to identify the dependability of the phase unwrapping path,and phase unwrapping process was guided by the distance tree.The result of the experiment shows that the algorithm is feasible and effective,and the path of phase unwrapping is always directed from the minimum distance value to the greater distance value.So in the worst case this algorithm can restrict the errors in the minimum local region.
