图像通信中一种低照度彩色图像增强算法
A Low Illumination Color Image Enhancement Algorithm in Image Communication
摘要
Abstract
In order to solve the problem of fuzzy and low brightness in color image,a new color image enhancement algorithm is proposed.First,a new transfer function is introduced to improve the traditional filtering. Then,in the RGB color space,the R,B and G components are enhanced by using the improved algorithm of the improved filter?ing algorithm and the adaptive histogram equalization algorithm(CLAHE). The color space is converted to HSV, and the brightness is compensated by the nonlinear function,the saturation is drawn out to a intensity level of 1.5 times of the original. Finally,the image color information are restored. Experimental results show that the new algo?rithm can enhance the image contrast,and make the image more high resolution.关键词
