| 摘 要： | 介绍了小波图像的分解和重构方法以及小波融合过程。采用Symlet小波变换融合方法对西安地区鲸鱼沟水库的TM4、TM5子图进行单尺度二维离散小波变换融合，并进行水库的边缘检测。对图像通过TM4分解的低频图与TM5分解的高频图像融合再与TM4影像原图比较，融合图像提取细节效果明显优于TM4原图像。

| Abstract: | This paper introduces wavelet decomposing and composing in image, and the process of wavelet transforms fusion in two images. Fusion and edge detection of Jingyugou reservoir remote image in Xi＇an area made based on Symlet wavelet transform. The low frequency of TM4 is fused with high frequency of TMS. Edge detection of the reservoir show the remote sensing fusion image of TM4 and TM5 is better than the one of TM4. |
