AN IMPROVED MASK-CUT PHASE UNWRAPPING ALGORITHM
College of Electronic Engineering, Naval University of Engineering, Wuhan 430033
Abstract In order to optimize the unwrapped result of those mask areas, an improved maskcut phase unwrapping algorithm is proposed. After the mask generation, those nonmask areas are unwrapped directly, then the “circle cancelling” method is performed during those mask areas to minimize the discontinuity, which can remove those “died area” and keep the unwrapped result continuous. The tests performed on InSAR and InSAS interferograms show that the improved algorithm removes the “died area” of the unwrapped result successfully and greatly enhances its quality.
