In this paper,a new image fusion algorithm based on lifting wavelet transform is presented. The source images are decomposed using lifting wavelet transform respectively. Aiming at the coefficients of low frequency and high frequency,this algorithm choose a different rule to fuse the image. To the low frequency,the spatial frequency based on the neighborhood add consistency check is elected as the fusion guide. And the absolute maximum based on detail coefficients is selected as the guide to the high frequency. After that the fused image is obtained by using inverse lifting wavelet transform. Taking the ratio space frequency error and the mean gradient as criterions,experimental results demonstrate that the algorithm is very effective and is able to fuse multi-source images.
