Multiscale versus multiresolution analysis for multisensor image fusion

In this paper, We propose a multisensor image fusion method based on the multiscale decomposition. In this representation, the redundant wavelet transform is performed on input images to emphasise the dominant details present at each scale. A fusion rule is applied between wavelet coefficients in order to produce a fused image. Two different fusion rules are used in the wavelet domain. A quantitative evaluation shows the superiority of our approach over the existing multiresolution method.
