Quality-Guided Phase Unwrapping Method Based on Placement of Branch Cuts

基于分支设置的质量导引相位展开算法

The results show that the Goldstein filtering method can improve effectively the distribution of residuals and branch cuts and raise the visual effects of the interferogram as well as the ratio of signal to noise.

结果表明：Goldstein滤波方法有效地减少了残点和枝切线的分布，提高了干涉图的视觉效果和信噪比。基于网络流的L1范数方法可以得到最优的全局解，但运算效率较低；
