Image Defogging Approach Based on Dark Channel Prior with Feedback Mechanism
Jianlong Xu · Journal of Information and Computational Science · 2014
Aimed at degradation of image gotten in misty weather, an image defogging algorithm based on dark channel prior with feedback mechanism is proposed. This algorithm can not only retain excellent treatment effect of the dark channel prior defogging algorithm on the image of non bright areas but also restore scene perfectly from the image with bright areas. Experimental results show that the algorithm can efficiently alleviate the color distortion caused in process of defogging the image with bright areas using dark channel prior algorithm, and make the image defogged smoother and more natural.
