    Abstract: This paper describes an unwrapping phase method based on region-segmentation and coding.The algorithm can easily unwrap noisy interferograms,but it will meet some problems when the phase contains aliasing.In addition,in order to perform the calculation easily when finishing region-segmentation,a method of encoding has been proposed.The main steps are:① Pretreatment with the medium and gradient-based adaptive filter in order that the segmentation can be carried out correctly;② The region-segmentation with the familiar algorithm;③ Encoding the regions from the previous step;④ Calculating the unwrapped phase by easy account.To verify the proposed algorithm,the algorithm has been tested with simulative data and actual data.
