Abstract:
Pixels from an image are sampled for gray world statistics. To avoid the effect of saturated regions, the color pixels are pruned based on predetermined criteria for individual and combined color channel values. If a predetermined percentage of the pixels are included in the gray world statistics, color channel gain is calculated and applied to the image for color balancing.
