MBIRJAX has a hyperspectral denoising algorithm based which denoises the image by projecting down the spectrum in each pixel onto a small sub-space of a few basis functions which are generated from the spectra from all the pixels of the image:

The result (with the correct dimension choice of the sub-space) is a heavily denoised image.
