Abstract

The ship inevitably formed the "V" shaped linear wake by the propeller to stir seawater during the voyage, and its wake can be extended to several kilometers behind the ship. In this paper, the information of ship wake was segmented from sonar image by image filter, image enhancement, fuzzy clustering algorithm and morphology method. Finally, using skeletonization algorithm, thinning algorithm and recursive modified Hough transform field method acquired the edge straight of the ship wake. The method could be the important foundation for the development of the new wake detecting and tracking technique.
