海岸线是区分海洋与陆地区域的基本线。由于区分不同的海岸线时的标准不同，因此，不同的海岸线在卫星影像上提取方法也各不相同。本文采用常用的边缘检测方法，如Sobel 算子、Roberts算子和Canny算子三种算法对人工海岸和沙质海岸线进行提取比较，并通过实验数据验证评价3种算子提取海岸线的效果。

The coast line is the basic line between the land and sea areas .Because of different coast when standards are different , therefore, different Coastline Extraction Method in satellite images also each are not identical .The traditional edge detection methods such as Sorel operator , Roberts operator and Canny operator three algorithms were compared on the extraction of artificial coast and sandy coast line , and validated by experimental data evaluation of three operator Coastline Extraction effect .
