Abstract

Concerning waterfront segmentation for unmanned ships when performing water surface target recognition and visual navigation tasks, this paper proposed a waterfront line extraction method based on improved region growing. First, the method segmented the image in the Lab color space to obtain a seed point candidate area. Then, it constructed the least squares problem to select the optimal initial seed point in the seed point candidate area, and got the threshold of growth rule by calculating the image standard deviation. Finally, it carried out the region growing, and extracted edge of the obtained water surface area, from which separating the waterfront line. It tested the waterfront sample images by this method, and evaluated the results by correlation coefficient and offset error. The experimental results show that the proposed method can extract the waterfront line in complex environment, and the method is robust and real-time.
