Colorful Image Colorization [PDF]

open access: yes, 2016
Given a grayscale photograph as input, this paper attacks the problem of hallucinating a plausible color version of the photograph. This problem is clearly underconstrained, so previous approaches have either relied on significant user interaction or resulted in desaturated colorizations.

Estimation of dye concentration by using Kubelka–Munk and Allen–Goldfinger reflective models: comparing the performance

open access: yesScientific Reports, 2023
If the relationship between the reflectance function (K/S) and dye concentration (C) is known, the color of the dyed textile (R∞) and C could be predicted from each other.
