Detection of Lake Shoreline in SAR Image Based on Wavelet
基于二进小波变换的SAR图像湖岸线提取

In the field of map production, flood surveillance, and change study of lakeshore, the lake shoreline must be detected. A new method is explored in this paper, which can detect the lake shoreline in SAR images. Using this method, The edge points are detected by Mallat' s Wavelet-based edge detection method firstly, and then the Gradient Vector Flow Active Contour Model is used to connect the edge points. The result of the experiment shows that method presented in this paper can restrain the interference of speckle noise, and detect the lake shoreline precisely.
