Wavelet-domain satellite image fusion based on a generalized fusion equation

A generalized wavelet domain image fusion method which imposes weights on each of the wavelet coefficients for improving the conventional wavelet domain approach is presented. The weights are controlled in the least-squares sense for enhancing the details while suppressing excessive high frequency components. In experiments with IKONOS and QuickBird satellite data, we demonstrated that the proposed method shows a comparable or better performance than conventional methods in terms of various objective quality metrics.
