New HSR framework enhances detail transfer from RGB to hyperspectral images

Researchers have developed a new framework for RGB-guided hyperspectral super-resolution (HSR) that addresses limitations in existing methods. This framework combines cross-modal flow alignment with model-based Gram-Schmidt orthogonalization fusion to improve the transfer of spatial detail from high-resolution RGB images to lower-resolution hyperspectral images. It is designed to be lightweight, interpretable, and flexible, supporting various spectral supports and scale factors without retraining. Experiments on the Real benchmark and a custom dual-camera setup demonstrate improved reconstruction accuracy and significantly faster processing times compared to existing learned fusion baselines.
