采用亮通道先验的低照度图像增强算法
Low Light Image Enhancement Algorithm Using Bright Channel Prior
摘要
Abstract
In order to improve the brightness and contrast of low illumination image,a low light image en-hancement algorithm based on bright channel prior is proposed in this paper.Firstly,the proposed algorithm comes up with bright channel prior in order to deal with flaw of the Retinex algorithms.Then the original RGB color image is converted to HSV color space,and the illumination image ofV component is evaluated by using bright channel and guided filter,as well as the contrast of the illumination image is enhanced by adaptive log-arithm correction.Finally,the enhanced image is converted to RGB color space.The experimental results show that the proposed algorithm is fast and effective,the overall image brightness and contrast is increased, as well as the image detail.Furthermore,the proposed algorithm overcome the color distortion and halos,and the enhanced color image is more bright and beautiful.关键词
