摘　　要：针对遥感高分辨率全色影像同低分辨率多光谱影像的融合,提出了一种在àtrous小波变换基础上,可以使边缘特征增强的遥感影像融合方法。实验证明,融合后的影像不仅在很大程度上保留了多光谱影像的光谱特征,还提高了空间分辨率,特别是边缘特征得到进一步增强。According to the fusion of high resolution panchromatic image and low resolution multi - spectral image, this paper put forward a method of remote sensing image fusion to enhance edge features based on atrous wavelet. The experiment showed that the results not only kept most spectral features of multi - spectral image, but also improved the spatial resolution. Especially, the edge features were further enhanced.
