A new method based on lifting wavelet transform and intensity-hue-saturation（IHS）transform for multi-sensor image fusion is presented.Firstly

all the characteristics of high-resolution’s low frequency are added to the multi-spectral image.Meanwhile the high-resolution panchromatic image is decomposed to the lifting wavelet planes

then the region is divided by edge influence factor.Finally

the fusion image is obtained by making the inverse IHS transform for the I component of the inverse lifting wavelet transform.The experimental results demonstrate that the performance of new method is better than IHS transform and wavelet transform（WT）.It not only preserves spectral information of the original multi-spectral image well

but also enhances spatial detail information.
