This paper proposes a new image fusion method for low-resolution multi-spectral image and high-resolution panchromatic image of the same area.Traditional HSI(hue-saturation-intensity) transformation method faces a problem namely color distortion,and traditional wavelet transformation has a problem of blurring.Therefore,this paper adopts a new method based on HSI and wavelet transform to solve the problem.First,the multi-spectral image is transformed into HSI space.Then,the intensity component of multi-spect...
