| 摘 要： | 首先介绍了遥感影像融合的理论和方法 ,然后在讨论多进制小波理论的基础上 ,提出了一种基于特征的多进制小波变换的影像融合算法 ,该算法根据待融合影像分辨率之比确定采用多进制小波 ,从而最大限度的利用了待融合影像的信息 ,防止影像信息的丢失。通过对具体影像的实验 ,证明融合后的影像最大限度地保留了待融合影像的光谱信息 ,同时提高了待融合影像的清晰度和空间分辨率。文中给出了SPOT全色影像与SPOT多光谱波段影像、SPOT全色影像与TM影像的融合结果 ,并与其他方法进行了比较 ,证明了本方法的优越性和自适应能力

| Abstract: | This paper introduces the theory and method for remote sensing images fusion.Based on the multi band wavelet theory,a scheme of remote sensing images fusion based on image feature is made in this paper.In this algorithm the number of bands for wavelet transformis decided on the resolution ratio among remote sensing images,so as to make best use of the information on remote sensing images to be fused and prevent the loss of image information.This method is experimented by using material images.In the proposed method all the spectral characteristics have been preserved,and the definition and the spatial quality of image have been improved. Experimental results including the fusion of SPOT panchromatic image and SPOT multi-spectral images,SPOT panchromatic image and Landsat (TM) images are presented.Compared with other methods,the proposed scheme is much better and it possesses more adaptability. |
