5.CONCLUSION AND PROSPECTS 
A new multispectral and panchromatic band merging method is 
provided by combining ICA transform with A trous wavelet. 
The experiment result shows that the method can improve the 
spatial information of original spectral bands effectively. But 
spectral distortion is still a problem in fusion result. In the 
future, our work is focused on establishing a more flexible 
fusion rule for information displacement.
