Abstract
This paper presents the results of the investigation on image fusion applied to data with significantly different spectral properties. The experiments with simulated and real data show that conventional fusion methods heavily distort geometrical shapes of features in case of fusion of data with different spectral characteristics. As a step forward to solve the problem, a novel fusion approach is proposed. The method uses the relationship between the Wavelet Transform Modulus Maxima (WTMM) corresponding to the same feature in the fusing images. The experiments showed advantages of the proposed method in areas of substantially dissimilar spectral characteristics of merging data. The found limitations of the method are discussed as well.
