Treffer: Luminance-Based Adaptive Color Saturation Adjustment.

A novel luminance-based adaptive color saturation adjustment method to strengthen video images without producing oversaturated or color contour artifacts is proposed in this paper. Based on the luminance information, the relations between luminance levels and maximum chrominance vectors in each subcolor are generated adaptively for each pixel, so that the upper bound of the allowed saturation factor for a pixel can be derived, and much vivid video image can be achieved.
