Image Haze Removal Using Dark Channel Prior and Inverse Image

MATEC Web of Conferences, 2016
Image haze removal using dark channel prior is prone to encountering color distortion in sky and brightness region. To solve the problem, we proposed an improved method based on inverse image and dark channel prior.
