Image dehazing base on two-peak channel prior

Haze is one of the major factors that degrade outdoor images. Removing haze from an image is a challenge problem. In this paper, a two-peak channel prior model is proposed for general image dehazing. Firstly, the estimation of medium transmission function is derived and analyzed comprehensively. Secondly, a new calculation method estimating atmospheric light is proposed for more robust dehazing with a new compensation parameter. The experimental results illustrate that the proposed method is able to achieve more satisfied dehazing results than two state-of-the-art methods.
