Researchers are developing new methods to adapt pre-trained RGB image denoisers for hyperspectral image restoration tasks. One approach uses a lightweight adapter to repurpose frozen RGB denoisers by projecting spectral information and then reconstructing the hyperspectral cube. Another method employs trainable tensor decompositions to separate convolutional filters into spatial and spectral components, allowing the spectral parts to be retrained for higher channel dimensionality. Both techniques aim to leverage the vast knowledge from large-scale RGB datasets to improve hyperspectral image processing, showing promising results that outperform hyperspectral-specific baselines.
