摘要：Contourlet transform can give the asymptotic optimal representation of edges and contours, so it can capture smooth contours and geometric structures in images much more efficiently than the wavelet transform. The nonsubsampled contourlet transform (NSCT) not only has multiresolution and multidirectional properties but also has shift-invariant property by contrast to the contourlet transform. A new method of fusing panchromatic (Pan) and multispectral (MS) remote sensing images was proposed based on NSCT and IHS transform. IKONOS images were used to verify its validity. The experiment results show that the proposed method has greatly improved spatial resolution and keep the spectral information, and is better than the fusion method based on CT and IHS
