     * More sophisticated learning-based automatic white balance algorithm.
     *
     * As REF: GrayworldWB, this algorithm works by applying different gains to the input
     * image channels, but their computation is a bit more involved compared to the
     * simple gray-world assumption. More details about the algorithm can be found in
     * CITE: Cheng2015 .
     *
     * To mask out saturated pixels this function uses only pixels that satisfy the
     * following condition:
     *
     * \( \frac{\textrm{max}(R,G,B)}{\texttt{range_max_val}} < \texttt{saturation_thresh} \)
     *
     * Currently supports images of type REF: CV_8UC3 and REF: CV_16UC3.
