ExplainS2A: Explainable Spectral-Spatial Duality Model for Fast Transforming Sentinel-2 Image to AVIRIS-Level Hyperspectral Image
ExplainS2A reformulates spectral super-resolution of multispectral images as spatial super-resolution using spectral-spatial duality and solves it with an explainable deep unfolding and fusion network for fast high-fidelity hyperspectral output.
