Pansharpening refers to the process of inferring a high resolution multispectral image from a high resolution panchromatic image and low resolution multispectral one. Although quite successful in terms of relative error, state-of-the-art pansharpening methods still introduce relevant color artifacts. The variational pansharpening model proposed by Buades et al. incorporates a nonlocal regularization term that takes advantage of image self-similarity, leading to signicant reduction of the above-mentioned color artifacts. </body> </html>
