Pansharpening techniques aim at fusing a low-spatial resolution multispectral (MS) image with a higher spatial resolution panchromatic (PAN) image to produce an MS image at high spatial resolution. Despite significant progress in the field, spectral and spatial distortions might still compromise the quality of the results. We introduce a restoration strategy to mitigate artifacts of fused products. After applying the principal component analysis transform to a pansharpened image, the chromatic…

MTF-Based Deblurring Using a Wiener Filter for CS and MRA Pansharpening Methods

A simple modification of component substitution and multiresolution analysis schemes where the interpolated MS image is replaced by its deblurred version, where the deblurring kernel is matched to the modulation transfer function of the MS sensor can significantly enhance the quality of the fused image.

MTF-tailored Multiscale Fusion of High-resolution MS and Pan Imagery

This work presents a multiresolution framework for merging a multispectral image having an arbitrary number of bands with a higher-resolution panchromatic observation, and demonstrates that a superior spatial enhancement is achieved by means of the MTF-adjusted fusion.

A Nonlocal Variational Model for Pansharpening Image Fusion

A new variational method for pansharpening is proposed which incorporates a nonlocal regularization term and two fidelity terms, one describing the relation between the panchromatic image and the high-resolution spectral channels and the other one preserving the colors from the low-resolution modality.
