Image fusion method base on variance

ZHAO Tian-yun (Department of Information Management,Zhengzhou University,Zhengzhou 450001,China)  
Image fusion is an integrated information processing technology,which mainly aims at improving the reliability of images through processing the redundant information and the definition of images through processing complementary information among several images.The paper puts forward a new fusion method based on variance,which divides the original images into several parts and fuses the best ones.Experiments show that it can sustain useful information,realize the complementation of information and therefore have such advantages as simple arithmetic,fast runtime and better effect.And its application in medicine is also explored,which further supports the methods advanced in the paper.
