Research output: Contribution to conferencePaper


In this paper, we propose a simple but powerful prior, color attenuation prior, for
haze removal from a single input hazy image. By creating a linear model for modelling the scene depth of the hazy image under this novel prior and learning the parameters of the model by using a supervised learning method, the depth
information can be well recovered. With the depth map of the hazy image, we can
easily remove haze from a single image. Experimental results show that the proposed approach is highly efficient and it outperforms state-of-the-art haze removal algorithms in terms of the dehazing effect as well.
