Masking Method Based on Morphological Operations for InSAS

Abstract

Image masking is an important step for interferometric synthetic aperture sonar (InSAS). The quality of mask will directly influence the accuracy of complex registration and phase unwrapping. In this paper, a novel masking method based on morphological operations for InSAS is proposed, which overcomes the shortcoming of the traditional masking methods that depend on complex registration. The experiment result of real data demonstrates the efficiency of the proposed method.
