Deep Gaussian Scale Mixture Prior for Spectral Compressive Imaging
Deep Gaussian Scale Mixture Prior for Spectral Compressive Imaging
In coded aperture snapshot spectral imaging (CASSI) system, the real-world hyperspectral image (HSI) can be reconstructed from the captured compressive image in a snapshot. Model-based HSI reconstruction methods employed hand-crafted priors to solve the reconstruction problem, but most of which achieved limited success due to the poor representation capability of …
