摘　　要：由于WorldView-2卫星的全色图像与多光谱图像的光谱覆盖范围不匹配,传统的图像融合方法如intensity-hue-saturation(IHS)、brovey transforms(BT),已不再适用于新型卫星WorldView-2的图像融合,故在SFIM(smoothing-filter-based intensity modulation)融合方法的基础上提出了一种改进的融合方法。实验结果表明:该方法能很好地融合WorldView-2卫星图像,在增强空间细节的同时能较好地保持光谱信息,较原来的SFIM方法有更好的融合效果。The panchromatic images do not match the spectral coverage of multi-spectral images for WorldView-2 and other new satellites.So the traditional image fusion methods,such as intensity-hue-saturation(IHS),brovey transforms(BT),are no longer suitable for new satellite image fusion.An improved fusion method is proposed based on the SFIM(smoothing filter-based intensity modulation)fusion method.Experimental results show that this method can well fuse WorldView-2 satellite images.The spectral information can be maintained while the spatial details are enhanced.The fusion results are better than the original SFIM method.
