COS2A: Conversion from Sentinel-2 to AVIRIS Hyperspectral Data Using Interpretable Algorithm With Spectral-Spatial Duality
COS2A converts 12-band Sentinel-2 images into 172-band AVIRIS-like hyperspectral images by combining a small deep-unfolding network with a coupled-NMF spatial super-resolution step.
