D$^\text{2}$UF: Deep Coded Aperture Design and Unrolling Algorithm for Compressive Spectral Image Fusion. (arXiv:2205.12158v1 [eess.IV])

Compressive spectral imaging (CSI) has attracted significant attention since
it employs synthetic apertures to codify spatial and spectral information,
sensing only 2D projections of the 3D spectral image. However, these optical
architectures suffer from a trade-off between the spatial and spectral
resolution of the reconstructed image due to technology limitations. To
overcome this issue, compressive spectral image fusion (CSIF) employs the
projected measurements of two CSI architectures with different resolutions to
estimate a high-spatial high-spectral resolution. This work presents the …
