Which color calibration algorithm?

Hi, Can someone give me a reference for the color calibration algorithm used here? Any research paper or links would be helpful. Thanks!

There is no paper we followed per se. Gowever using non-linear-least-squares optimization in Lab* is fairly well known and the underlying mathematics of which is described here: http://www.babelcolor.com/index_htm_files/RGB%20Coordinates%20of%20the%20Macbeth%20ColorChecker.pdf

How do you find correspondences between actual palette and captured palette in order to run non linear optimization?
