Specular Reflection Image Enhancement Based on a Dark Channel Prior

In this paper, we propose a specular highlight image enhancement algorithm based on dark channel prior to solve the problem of information loss in images real scenes. First, is algorithm, and moving window minimum filter used estimate global illumination component. Then, weighted function local pixel color difference introduced halo artifacts image. improved guided optimize transmittance, which improves computational efficiency algorithm. Finally, brightness adjusted by CLAHE enhance details Experimental results show that method can effectively images, its processing are obviously better than those other algorithms.
