Namespace

Emgu.CV.XPhoto

Assembly

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]: Saturation[I]= max(R,G,B)-min(R,G,B) / 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.
