Inshore ship detection has significant practical meaning,especially for the target change detection.However,it is difficult to realize the inshore ship detection utilizing the traditional area-based method because of the complex background.A partial Hausdorff distance measurement based on image contour matching method is proposed,which is fit for the inshore ship search and location.The main characteristics of the proposed method are,1) a fast distance transform and pyramid decomposition are used to speedup the Hausdorff distance matching;2) a pyramid is constructed from the original image to avoid the over-sample of contour.Experiments with images of satellite are carried out to validate and analyze the proposed method.
