InSAR Phase Unwrapping Method Using Quality Map with Residues
|
Abstract:
We propose an algorithm which optimizes the way of choosing quality threshold according to the distribution of the residues.All the pixels of the wrapping phase figure are classified by this threshold into two types,high quality pixels and low quality pixels,and given different weights and then unwrapped.Experimental results show that the proposed algorithm has the advantages of less information loss,clearer guide line,fewer manual works,and its precision is superior to some of the conventional algorithms such as the branch-cut algorithm.
