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 CV_8UC3 and CV_16UC3.
