| 摘 要： | 以河北省唐山市曹妃甸地区的海岸线为研究对象，选取 ETM 遥感影像进行低通滤波、中值滤波以及均值平滑处理。运用边缘检测方法中的修复归一水体指数算法（MNDWI）和Soble 算法，实现了对曹妃甸地区的海岸线的自动提取。两种提取方法相比较的结果表明， Soble 算法比修复归一化水体指数法提取精度更高，更适合曹妃甸地区的海岸线提取。

| Abstract: | This article takes the Hebei Province CaoFeiDian coastline as the object of study. Processing methods of the ETM remote sensing image are Low-pass filter,median filter and mean smoothing. Using edge detection method of repair to the water body index algorithm（MNDWI）and Soble algorithm,the article implements the automatic ex-traction of CaoFeiDian coastline. Compared two extraction results show that the repair Soble operator method has a higher precision,it suitable for coastline extraction of CaoFe iDian area. |
