Merging multispectral and panchromatic images with respect to edge information

A new technique is developed for the data fusion of multispectral image and panchromatic image. The intensity component of fusion image is modified by combine multispectral information and high-resolution information, which is determined by image edge intensity. The fusion image is reconstructed by means of the inverse IHS transform. Experiment comparison shows that our method performing better in preserving spatial resolutions and color content than that of traditional IHS transform technique and wavelet transform fusion method.
