The image acquisition process is affected by many factors so that the quality of the original image is difficult to meet the actual requirements of image processing. In order to improve the quality of the image, an improved Retinex based image enhancement algorithm is designed. First of all, the current research status of image enhancement is analyzed, and then the working principle of Retinex algorithm is analyzed, and its shortcomings are improved. Finally, the improved Retinex algorithm is applied to image enhancement, and the simulation experiment is carried out with specific images. The results show that the improved Retinex algorithm can greatly improve the visual effect of the image, and the quantitative analysis index is also better than the other image enhancement algorithms, and has a more extensive application value.
