  This paper reviews the NTIRE 2020 Challenge on NonHomogeneous Dehazing of
images (restoration of rich details in hazy image). We focus on the proposed
solutions and their results evaluated on NH-Haze, a novel dataset consisting of
55 pairs of real haze free and nonhomogeneous hazy images recorded outdoor.
NH-Haze is the first realistic nonhomogeneous haze dataset that provides ground
truth images. The nonhomogeneous haze has been produced using a professional
haze generator that imitates the real conditions of haze scenes. 168
participants registered in the challenge and 27 teams competed in the final
testing phase. The proposed solutions gauge the state-of-the-art in image
dehazing.
