In order to solve the problem of image blurred and edge and detail reduction caused by scattering and reflection of water droplets in cloud field during the icing wind tunnel test

the homomorphic filtering algorithm and the dark channel prior dehazing algorithm are used to deal with different liquid water content images respectively

and the dehazing quality is evaluated by subjective and contrast enhancement methods. The results show that both defogging algorithms can improve the image quality to some extent. Comparing the two algorithms

the dark channel prior algorithm has better defogging effect in images with different liquid water contents.
