摘要
在分析海岸线提取算法基础上,以环渤海的Landsat7 ETM+影像为数据源,以基岩海岸线和淤泥质海岸线两种典型的海岸线为研究对象,采用Sobel边缘检测算法、阈值分割法和K最邻近分类算法进行海岸线提取实验。通过实验对比分析,归纳和总结了针对不同类型海岸线提取算法的适用性。
Based on the analysis of the coastline extraction algorithm, the paper takes the Landsat7 ETM＋ image of Bohai Sea Riving Area as data source and studies such two typical coastlines, bedrock coastline and muddy coastline. Then carries on the coastline extraction experiment by using Sobel edge detection algorithm, threshold segmentation method and K-Nearest Neighbor. According to the experimental analysis, the applicability of the extraction algorithm for different types of coastline has been summarized.
