Abstract

According to the characteristic of low visibility of night image, we proposed an improved image enhancement method based on multi-scale Retinex. In our method, we replace the Gaussian filter as Blur filter, and replace logarithm gain as linear gain to reduce the computational complexity. The proposed algorithm first segment color image into three independent R, G, B channels, and then employ our improved multi-scale Retinex algorithm to enhance contrast of each channel. Finally, the enhanced image is given by recombining the three R, G, B enhanced results. A large number of experiments show that the proposed algorithm can quickly and efficiently improve the contrast of the night image and has a better visual effect than that of the similar method.
