| 摘 要： | 由于高分辨率遥感影像上靠岸船舶的灰度、纹理特征往往和港口地面接近,与离岸船舶相比,其自动提取与识别相对更为困难,为此,为离岸、靠岸船舶的提取设计了不同方案。实验证明了方法的有效性。

| Abstract: | Different routes are designed and applied to extract the two kinds of ships in this paper. The method can be divided into three main steps: extract water polygons with histogram segmentation, extract holes in the water polygons with morphological operations as the possible sailing ships, and extract possible moored ship with the identification of salients along the water boundary, and then screen real ships out of these possible ships with more shape constraints. Experiments give good results. |
