Hue-based color saturation compensation

~ An e/ficient color saturation compensation nrethod is proposed in this paper. I t uses U hire-based conipensation guin to nmd<v the chrominance signals. The hue-based conipensation gain is ohtainedfrorn the weighted lunriiiurice rnodlfication ratio afer nanlitiear contrast enhancement. The ivei~hringfiinctian is associated with the hrrman colorpe~ceprio,r. It cotnpensates the color satirrafion on the basis ofthe hire. Test results show that this inethad is rffctive in the i i~~p~avet r~enr of the color irnuge yiralities’. Index Terms Color saturation compensation, Human color perception, Contrast enhancement.
