This paper introduces the lifting wavelet transform and proposes a new image fusion algorithm based on lifting wavelet transform.Aiming at the different characteristic of the coefficients of low frequency and high frequency after lifting wavelet transform,this algorithm chooses a different fusion rule to fuse the image,and obtains the fusion image by inverse lifting wavelet transform.By analyzing the fusion image with visible and infrared image and comparing the other fusion algorithms,the experimental result shows that this algorithm can clear the fusion image and improve spatial presentation.
