Abstract: 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.
