摘要
利用遥感技术确定海岸线位置的问题受到关注由来已久,就其在国内外的研究现状做了介绍,利用小波边缘检测算子提取出黄河三角洲河口区2004年Landsat TM图像的海岸线位置;在分析小波算子与传统边缘提取方法相比的优点的同时,并就其存在的不足提出了今后的研究重点。
Using remote sensing technique to determine coastline's position has been a problem received long attention.The paper present the development of research on this problem at home and abroad firstly.By using wavelet edge detection operators to extract the coastline of the Yellow River delta river estuary based on Landsat TM in 2004 and got more precise coastline through non-maximum depression,the paper illustrated the advantages and disadvantages of edge detection operators.Results showed that wavelet edge detection operators were more functional than traditional operators to extract precise coastline.The research emphases in future were also pointed out.
