Active illumination compressive 4D spectral video imaging system

Not Accessible

Your library or personal account may give you access

Abstract

A compressive 4D spectral video imaging system is proposed and verified in experiments. Active LEDs illumination scanning and DMD binary patterns are adopted with a new coding strategy to modulate a 4D scene in space, spectra, and time. Compressive sensing algorithm is applied to reconstruct 4D image-cube from a 2D grayscale compressive snapshot.
