Zhong Huang · Jisuanji gongcheng · 2012
In order to remain the hue invariability during the color image enhancement,this paper presents an enhancement algorithm of color image based on RGB gray value scaling.It uses the twicing function to enhance the maximum of RGB pixel values,and gets the scaling k to adjust the RGB value with gain acquired.Experimental results show that the algorithm is efficient for enhancement of color image with compression at different quality,and outperforms the existing algorithm in most cases.
