Abstract

Aiming at the phenomenon that the low luminance image is bright and the the color is not balanced, this paper had carried on the study of the color recovery operator of the low illumination image with improved pyramid fusion technology. The algorithm combined the original image and the pretreatment diagram with the defog model or MSRCR to fuse the color contrast, saturation and brightness into the pyramid algorithm with the gold tower technique, and assigned different weight parameters according to the information of the image, which could effectively solve the traditional low-light image color enhancement problems. And it proposed a Fourier smoothing filter with weighted least squares in the CIELAB channel to smooth the image of the L channel, set the parameters of different tone mapping to enhance the image detail information, so that the information of the image in night vision is more Conspicuous and true. It selected three different types of images for experimentation, and improved the quality of graphics. It also shows that this algorithm has some universality.
