// C++: class LearningBasedWB
/**
 * 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.
 *
 * Member of `Xphoto`

/**
 * Implements the feature extraction part of the algorithm.
 *
 *     In accordance with CITE: Cheng2015 , computes the following features for the input image:
 *     1. Chromaticity of an average (R,G,B) tuple
 *     2. Chromaticity of the brightest (R,G,B) tuple (while ignoring saturated pixels)
 *     3. Chromaticity of the dominant (R,G,B) tuple (the one that has the highest value in the RGB histogram)
 *     4. Mode of the chromaticity palette, that is constructed by taking 300 most common colors according to
 *        the RGB histogram and projecting them on the chromaticity plane. Mode is the most high-density point
 *        of the palette, which is computed by a straightforward fixed-bandwidth kernel density estimator with
 *        a Epanechnikov kernel function.
 *
 * @param src Input three-channel image (BGR color space is assumed).
 * @param dst An array of four (r,g) chromaticity tuples corresponding to the features listed above.
