This paper firstly made a brief introduction of several methods for information fusion. and also the paper raised a comparison of the fused images which were merged by wavelet transform

PCA an HIS methods

in spatial quality improving and spectral information preserving respectively. Then

the paper introduced several new fusion methods of Multisensor Remote Sensing data

Using algebra calculation and linear calculation

avoid lost spectral information of traditional method

and develop resolution of image

and author performed a discussion on the relationship between several methonds and the fused results

specially made useful advantage of image and overcome disadvantage of image in the fused process. Finally the article introduced a fusion framework of Multisensor Remote Sensing

the author particularly studied every process

include image match

image sharpness enhancement

image fusion

image color enhancement process. The framework is used for a big amount data and a large range image. The article introduced the application of image fusion.
