Panchromatic and Hyperspectral Image Fusion: Outcome of the 2022 WHISPERS Hyperspectral Pansharpening Challenge

This article presents the scientific outcomes of 2022 Hyperspectral Pansharpening Challenge organized by 12th IEEE Workshop on Image and Signal Processing: Evolution in Remote Sensing (IEEE WHISPERS 2022). The aims at fusing a panchromatic image with hyperspectral data to get high spatial resolution cube same while preserving spectral information data. Four datasets acquired PRISMA mission owned managed Italian Space Agency have been prepared for participants. They are made available benefit community. Each dataset contains different resolutions. More than 100 registrations received event. teams submitted their outcomes. Since no team actually outperformed baseline provided organizers, challenge was declared inconclusive winner recognized.
