ABSTRACT:
Pixels from an image are sampled for gray world statistics. To avoid the effect of saturated regions, the pixels are pruned. If a predetermined percentage of the pixels are included in the gray world statistics, color channel gain is calculated and applied to the image. As a result, color balance is achieved in a simple and efficient manner.
