Abstract

Waterside line information extraction is a foundational task in studying mudflat sedimentation/erosion variation. This paper puts forward a new identification method more suitable for the ring waterside line information detection than the traditional Hough-like method. The authors firstly detected edges from the image segmentation achieved by the waterside line gray gradient information, then dilated and filled the interior by mathematical morphology to connect edges, and finally constructed segment-shaped structural elements to achieve a continuous and smooth waterside line. Experimental results show that not only the method is simple, but also the extracted waterside line is ideal.
