R2H-Diff: Guided Spectral Diffusion Model for RGB-to-Hyperspectral Reconstruction
Songyu Ding, Ronggiang Zhao, Mingchun Sun +1
RGB-to-hyperspectral image reconstruction is a highly ill-posed inverse problem, since multiple plausible spectral distributions may correspond to the same RGB observation. Existin…
