Abstract: Image fusion is the process of matching two or more images that from the same scene derived which from different time，different sensors or different views of angle，mainly used to eliminate the variation of position of targets from different sensor images.Give a new medical image fusion algorithm which in the basis of researching some basic algorithms.The new mage fusion algorithm is based on lifting scheme wavelet transform.Decomposed wavelet components of the original images are used to impose the speed of image fusion.Experiment results show that the algorithm is effective and accuracy.

Key words: wavelet-transform, image fusion, lifting scheme, invariant moments
