Secondly ,the main steps in image fusion process are described and image fusion rule based on lifting wavelet transform are summarized.

Then fuse the wavelet coefficients based on window according to fusion rules.

After analyzing some fusion rules based on Wavelet Transform and their effects,this paper presents a new method of Medical Image Fusion.

The concept of multi-focus image fusion and ordinary image fusion methods are introduced,then the principle of image wavelet decomposition,the process of multi-focus image fusion by using wavelet analysis and different fusion rules are presented.

Based on the analysis of existing wavelet image fusion method and with an aim at the selection of high and low frequency fusion rules,the paper presents a new image fusion algorithm based on wavelet multi-resolution decomposition.

The two kinds of fusion rules,including pixel-based and region-based local variance,are discussed,and then modified fusion rules are proposed.

Image fusion algorithms and fusion rules are important for image fusion technology.

Aimed at decision-making information system of a certain aero-engine fault,the paper firstly sought its CADS based on maximal distribution,then introduced the method of rule fusion to obtain all decision rules under different conditions,and the history faults were recognized accordingly with a higher rate of identification.
