Abstract :
The HDR tone-mapping operators have evolved rapidly in recent years. Moreover, the physiology-influenced methods have been researched lately as a separate branch. Our contribution to this field is the application of hue correction according to the subjective effect referred to as the Bezold-Brücke hue shift. We introduce a mathematical approach for the correction of this shift. The correction is performed in a colour space given by the gamut base colours R,G,B (primaries) and white point. This approach is applied to the traditional physiology-influenced operators.
