Aiming at the selection of fusion rules of multiple images,a novel fusion algorithm of multiple images based on fast integer lifting wavelet transform is proposed.Firstly,the integer lifting wavelet transform is used to perform a multi-scale and multi-orientation decomposition of each input image.And then,the integer lifting wavelet coefficients for the fused image can be obtained by means of new fusion rules in different frequency bands.Finally,the fused image is reconstructed by the inverse integer liftin...
