Abstract:
Ship wake detection has a broad range of applications in marine traffi c control and national security. Current methods were developed based on SAR(Syn thetic Aperture Rodar) ima ges. As a result they have two significant disadvantages: the information is not intuitive and the corresponding algorithms are relatively complex. This paper p roposes a novel ship wake detection method based on optical images. Firstly, it judges whether there are ship wakes through texture analysis. Then it uses a str ipe enhancement algorithm to enhance the characteristics of a ship wake. Finally , it applies Radon transform to detect ship wakes and optimizes detection result s. C ompared with existing methods, the proposed method is more appropriate for the t ask and has lower complexity. The method was tested on pictures with wakes and d emonstrated effective wake detection.
