 提出了一种基于可操纵金字塔和IHS变换的遥感影像融合方法。对多光谱(MS)图像的强度分量和全色图像(PAN)分别进行可操纵金字塔分解,针对金字塔分解后的低频、高频和各带通子图像分别采取不同的融合规则获得融合子图像,再先后通过可操纵金字塔框架下的逆变换和IHS逆变换得到融合图像。实验结果表明,该方法在增强影像细节信息、保持光谱特性方面比传统的IHS融合法效果更好。 更多还原

【Abstract】 This paper proposed a new image fusion method based on steerable pyramid and IHS Transformation. The intensity component of multispectral image(MS) and panchromatic image(PAN) was decomposed respectively by steerable pyramid transformation. Different rules are used to fuse sub-images of low frequency, high frequency, and band pass, and then the fused multispectral image could be reconstructed by inverse steerable pyramid and IHS transformation. The experiment results show that the new method is ... 更多还原
