  Images captured in hazy weather conditions often suffer from color contrast
and color fidelity. This degradation is represented by transmission map which
represents the amount of attenuation and airlight which represents the color of
additive noise. In this paper, we have proposed a method to estimate the
transmission map using haze levels instead of airlight color since there are
some ambiguities in estimation of airlight. Qualitative and quantitative
results of proposed method show competitiveness of the method given. In
addition we have proposed two metrics which are based on statistics of natural
outdoor images for assessment of haze removal algorithms.
