This is a simple Matlab implementation of the chromadapt function presented in Matlab2017b. The function adjusts color balance of RGB image with chromatic adaptation based on different chromatic adaptation transforms (e.g., Bradford, von Kries, CAT2000).
Note: we assume that the input image in the standard RGB without applying tone mapping or any camera picture style (i.e., after applying the color correction matrix to get the XYZ values, we assume there is only gamma curve applied according to the standard RGB in Ref. [1,2].
