1. A method for local value adjustment, comprising: identifying a hue and saturation for each pixel of an image; determining whether the hue and saturation for each pixel fall within a predetermined set of hue and saturation combinations; and selectively increasing a perceived contrast of the image around a mean brightness for a localized region by applying a transfer function to each pixel of the image based upon the determination of whether the hue and saturation of the pixel fall within the predetermined set of hue and saturation combinations.
