| Abstract: | 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 de... |
