// C++: class GrayworldWB
/**
 * Gray-world white balance algorithm
 *
 * This algorithm scales the values of pixels based on a
 * gray-world assumption which states that the average of all channels
 * should result in a gray image.
 *
 * It adds a modification which thresholds pixels based on their
 * saturation value and only uses pixels below the provided threshold in
 * finding average pixel values.
 *
 * Saturation is calculated using the following for a 3-channel RGB image per
 * pixel I and is in the range [0, 1]:
 *
 * `$$ \texttt{Saturation} [I] = \frac{\textrm{max}(R,G,B) - \textrm{min}(R,G,B)
 * }{\textrm{max}(R,G,B)} $$`
 *
 * A threshold of 1 means that all pixels are used to white-balance, while a
 * threshold of 0 means no pixels are used. Lower thresholds are useful in
 * white-balancing saturated images.
 *
 * Currently supports images of type REF: CV_8UC3 and REF: CV_16UC3.
 *
 * Member of `Xphoto`
