Paper Abstract

This paper presents a novel method for image fusion that integrates improved HIS and curvelet transform, and uses it to fuse the IKONOS images. Firstly, red band is added to panchromatic band with weights to obtain a new panchromatic band, and blue, green and near-infrared bands are stacked to form the RGB space, which is used for converting to HIS space later. Secondly, the new panchromatic band and intensity component carry on curvelet transform respectively. Then fuse the coefficients in the corresponding scales to generate a new intensity component. Finally, the inverse HIS transform is applied to generate the fusion image. To prove the superiority of this method, this paper uses several parameters to assess the image comparing with other fusion images. The results show that the proposed method can increase the information entropy, decrease the spectrum distortion of the fused image, and improve the structural similarity between the fused image and the original multispectral image. So all above prove that the integrated method can enhance the fusion quality efficiently.
