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.
% By Mark Ruzon from C code by Yossi Rubner, 23 September 1997.
