Abstract :
A principally new technique for fast fusion of multiresolution satellite images with minimal colour distortion is presented in the paper. This technique allows multispectral image reconstruction with resolution higher than resolution of the panchromatic image. It is based on combination of a method for super-resolution image reconstruction and an algorithm for image fusion based on global regression. Superresolution image reconstruction is based on simultaneous processing of several multispectral images to reconstruct a panchromatic image with higher resolution. This method is near optimal in a minimum mean squared error sense of image restoration.
