Low-light Image Enhancement by Combining Brightness and Contrast Processing
In this paper,a low-light image enhancement by combining brightness and contrast processing algorithm is proposed to solve low uneven brightness,poor contrast and loss of image details problems.Firstly,homomorphic filtering is introduced to remove noise.Secondly,the homomorphic filtering image is processed separately,and the sub-image 1 is converted from RGB to HSV,and the V-channel is enhanced jointly.The limited contrast adaptive histogram equalization process is carried out for sub-image 2.Finally,sub-image 1 and sub-image 2 are weighted to get the final enhanced image.The experimental results show that the proposed algorithm has obvious advantages and can improve the quality and visual effect of low-light image better than other algorithms.
