Super-Resolution of Sentinel-2 Images Using a Geometry-Guided Back-Projection Network with Self-Attention
Ivan Pereira-Sánchez, Daniel Torres, Francesc Alcover +4
The Sentinel-2 mission provides multispectral imagery with 13 bands at resolutions of 10m, 20m, and 60m. In particular, the 10m bands offer fine structural detail, while the 20m ba…

Model-Guided Network with Cluster-Based Operators for Spatio-Spectral Super-Resolution
Ivan Pereira-Sánchez, Julia Navarro, Ana Belén Petro +1
This paper addresses the problem of reconstructing a high-resolution hyperspectral image from a low-resolution multispectral observation. While spatial super-resolution and spectra…

Multi-Head Attention Residual Unfolded Network for Model-Based Pansharpening
Ivan Pereira-Sánchez, Eloi Sans, Julia Navarro +1
The objective of pansharpening and hypersharpening is to accurately combine a high-resolution panchromatic (PAN) image with a low-resolution multispectral (MS) or hyperspectral (HS…
