中文摘要：

采用a’trous小波与HIS变换相结合的方法对Aster多光谱影像和资源二号全色影像进行融合实验和评价,并与传统的HIS变换和小波变换融合方法加以对比。结果表明：a’trous小波与HIS变换相结合的融合效果最好,吸取了两种单一融合方法的优点,不仅较大程度上提高了原始影像的空间细节表达能力,而且很好地保留了原始影像的光谱信息,为遥感应用提供了更精确的数据。

英文摘要：

The paper used a ＇ Trous wavelet and IHS transformation method to fuse the Aster multi-spectral image and Resource-2 panchromatic image, contrasted with the traditional method of HIS transformation and a＇ Trous wavelet transformation. The results showed that the method based on a＇ Trous wavelet and IHS transformation owned the best fusion effect. It greatly assimilated the advan- tages of the single fusion method, largely enhanced spatial detail information of the original image and reserved spectral information of the original multi-spectral image well, so could provide more precise data for remote sensing application.
