We present a fast reconstruction algorithm for hyperspectral images, utilizing a small amount of data without the need for any training. The method is implemented with a dual disperser hyperspectral imager and makes use of spatial-spectral correlatio

International audience; Recently we demonstrated the reconstruction of a hyperspectral datacube with 110 wavelength bands from 10 camera acquisitions [1] . The implementation of this scheme, similarly to compressed sensing, relies on spatial- spectra

International audience; We present a novel acquisition scheme based on a dual disperser architecture, which can reconstruct a hyperspectral data cube using many times fewer acquisitions than spectral bands. The reconstruction algorithm follows a quad

International audience; We consider the problem of hyperspectral cube reconstruction with a new controllable imaging system. The reconstruction with a small number of images acquired with different configurations of the imager avoids a complete scann
