Multispectral image fusion and merging using multiscale fundamental forms

In this paper, a new multispectral image wavelet representation is introduced, based on multiscale fundamental forms. This representation describes gradient information of multispectral images in a multiresolution framework. The representation is in particular extremely suited for the fusion and merging of multispectral images. For fusion as well as for merging, a strategy is described. Experiments are performed on multispectral images. In these experiments, Landsat Thematic Mapper images are fused and merged with panchromatic images. The proposed techniques are compared to wavelet-based techniques described in the literature.
