Description: ％ function [L, a, b] = RGB2Lab(R, G, B)
％ RGB2Lab takes matrices corresponding to Red, Green, and Blue, and
％ transforms them into CIELab. This transform is based on ITU-R
％ Recommendation BT.709 using the D65 white point reference.
％ The error in transforming RGB -> Lab -> RGB is approximately
％ 10^-5. RGB values can be either between 0 and 1 or between 0 and 255.
