Outdoor captured scenes are degraded by atmospheric particles and water droplets. Due to scattering and absorption effects in the atmosphere, the degraded images lose contrast and color fidelity. Performance of the computer vision algorithms bound to suffer from low-contrast scene radiance. In many single image dehazing models, the larger the deviation in estimation of the key parameters such as transmission map and atmospheric light leads to halo artifacts and loss of fine details in the dehazed image. The available models assume that the scattering light is independent of wavelength, as the size of the atmospheric particles is larger compared to the wavelength of light. The model presented in this paper emphasized on appropriate estimation of intensified transmission map from the hazy images by exploiting the scattering coefficient in order to address the issues of haze concentrations. Experiments conducted on thick and thin hazy images provide an optimal estimation of the model parameters, which can be applied directly in real-time situation. The available models are observed to be inconsistent sometimes in the enhancement of contrast, saturation and color information either together or independently. The proposed model addressed these issues by extracting the haze-relevant features from the hazy images such as Hue disparity, Contrast and Darkness which yield more vivid saturation results. Moreover, the proposed model addressed different haze densities in the scene without the use of refinement filters.
