P. Scheunders et S. De Backer, Fusion and merging of multispectral images with use of multiscale fundamental forms, J OPT SOC A, 18(10), 2001, pp. 2468-2477
A new multispectral. image wavelet representation is introduced, based on m
ultiscale fundamental forms, This representation describes gradient informa
tion of multispectral images in a multiresolution framework. The representa
tion is, in particular, extremely suited for fusion and merging of multispe
ctral images. For fusion as well as for merging, a strategy is described. E
xperiments are performed on multispectral images, where Landsat Thematic Ma
pper images are fused and merged with SPOT Panchromatic images. The propose
d techniques are compared with wavelet-based techniques described in the li
terature. (C) 2001 Optical Society of America.
