Sensor-Adaptive Infrared Spectral Reconstruction with Plug-and-Play Diffusion Priors
Alireza Siyavashi, Jon Schlipf, Sebastian Reiter, Inga Fischer, Christian Wenger, Christian Herglotz
Hyperspectral sensing enables material identification; however, state-of-the-art spectrometers are costly and bulky, which limits their use in mobile applications. We address this by proposing sparse spectrum reconstruction from narrowband photocurrents using a pseudoinverse-guid…
