摘　　要：为了应用ALOS遥感影像调查浙江省德清县水域分布,首先采用小波变换、GS变换和高通滤波三种影像融合方法,分别对已配准的ALOS多光谱与全色波段影像进行融合;然后采用监督分类方法分别对融合前后影像提取水体信息,通过比较这三种融合方法在水体信息提取的效果,给出了适于水体信息提取的影像融合方法。In order to apply the remote sensing image ALOS to investigate the regional distribution of water in Deqing County of Zhejiang Province,firstly,the paper used three kinds of image fusion methods as wavelet fusion,GS fusion and HPF fusion to fuse the ALOS Multispectral images and panchromatic band images which were registered respectively. Then we used supervised classification method to extract the water information before and after the fused images respectively. By comparing the effects of water information extraction applied by three kinds of fusion methods,the paper has found out the suitable method for image fusion in water information extraction.
