Abstract:A novel method of image fusion based on the nonsubsampled wavelet-contourlet transform is proposed,combined with the merit of à trous transform,based on the recently developed nonsubsampled contourlet transform,which can offer a trait of flexible multiscale and shift-invariant simultaneity. The high and low frequency-coefficients are obtained by decompose the aeronautic image with the nonsubsampled wavelet-contourlet transformation. Then,according to the different coefficient characters,these coefficients are syncretized by using different fusion algorithms of weighted average. The experimental results show that the new method makes a better fusion result compared with the traditional transform methods.
