Reconstructions of the transmission spectra of five drinks. (a) Photograph of drink samples of five colors: pink, yellow, light yellow, blue, and purple. (b)–(f) Reconstructed transmission spectra of drinks. Dashed black lines represent GT spectra, and solid lines, except for light gray, represent the reconstructed transmission spectra using the DL architecture. Solid light gray lines represent the reconstructed transmission spectra using the numerical optimization method, sparse recovery (SR).
