一种遥感图像中海岸线的提取方法

Method of Extraction of Coastline in Remote Sensing Images

针对遥感图像中海水和陆地区域分割和海岸线提取的问题,提出了新的区域分割和边界提取。首先对目前存在的分割技术进行分析,确定这些方法的局限性和缺陷,然后回归到最基本的阈值分割和边缘检测技术,并受这些基本算法的启发提出一种边界寻找和阈值分割的方法,并通过实验证明了这种方法在进行海陆分割和海岸线的提取方面的有效性,最终实现了海陆分割和海岸线的提取。

Aimed at the segmentation between the sea and the land in remote sensing images and the ques- tion of the extraction of the coastline, a new method is proposed. Firstly, the existed methods are analyzed and the limitations and shortcomings are determined. Then the most basic methods are adopted such as threshold seg- mentation and edge detection technology. Enlightened by the basic method, an edge-search method and a thresh- old segmentation method are proposed. Experimental results show that they are effective on segmentation be- tween the sea and the land and the extraction of the coastline. Finally, segmentation between the sea and the land and the extraction of the coastline are realized.
