Parallel Dictionary Reconstruction and Fusion for Spectral Recovery in Computational Imaging Spectrometers

Computational imaging spectrometers using broad-bandpass filter arrays with distinct transmission functions are promising implementations of miniaturization. The number of filters is limited by the practical factors. Compressed sensing is used to model the system as linear underdetermined equations...
