A phase unwrapping method based on minimum cost flows method in irregular network

摘要

In the process of unwrapping phase images with high noise, traditional algorithms and derivative methods have many problems: for example, the error of noise region is transferred to other regions, and affects the extraction of useful information. In order to resolve this problem, we realize a phase unwrapping method on the minimum cost flows algorithm based on irregular network. This method is that low-quality phases are eliminated from interferogram and only high-quality phases are processed, so it can avoid the effect that low-quality are processed, so it can avoid the effect that low-quality regions make on high-quality ones, and assure phase unwrapping of the high-quality regions, then acquire good results.
