The goal of spectral imaging is to capture the spectral signature of a target. Traditional scanning method for spectral imaging suffers from large system volume and low image acquisition speed for large scenes. In contrast
computational spectral imaging methods have resorted to computation power for reduced system volume
but still endure long computation time for iterative spectral reconstructions. Recently
deep learning techniques are introduced into computational spectral imaging
witnessing fast reconstruction speed
great reconstruction quality
and the potential to drastically reduce the system volume. In this article
we review state-of-the-art deep-learning-empowered computational spectral imaging methods. They are further divided into amplitude-coded
phase-coded
and wavelength-coded methods
based on different light properties used for encoding. To boost future researches
we've also organized publicly available spectral datasets.
