Low Hluminance Image Enhancement Algorithm Based on Improved Defogging Technology

To achieve low ilumination image enhancement,this paper proposes a low ilumination image enhancement algorithm based on the technology of fogging,First,the anti color operation is applied to the low illumination image,then the foggy removal is performed on the anti color image,and the anti color operation is executed again to obtain the output image.Then,in the YCbCr color space,a detail enhancement network is constructed,the luminance information is enhanced with the parabolic function,the low brightness region is stretched,the brightness value of the bright region is not changed,and the color information is kept constant.The experiment proves that this method can improve the overall details of the image and avoid the traditional side.The problem appeared in the law has a good visual effect.
