基于IHS对偶树复小波变换的遥感图像融合方法

In this paper, we introduce a new method based on IHS and the dual-tree complex wavelet transform. Firstly, transform the multispectral image into the IHS components, decomposing the panchromatic and the intensity component into dual-tree wavelet planes, replacing the approximation image of the panchromatic decomposition by that of the intensity decomposition, then performing an inverse dual-tree wavelet transform to obtain a new intensity image, At last, performing the inverse IHS transform to get the fusion image. This method integrates the advantages of both the IHS techniques and the dual-tree complex wavelet techniques to reduce the colour distortion of IKONOS fusion result.
