Abstract: Because of light scattered by the suspended particles in the atmosphere, photographs taken in the foggy day look gray are lack of visibility. In order to unveil the clear image’s structures and colors, it proposes a new algorithm based on the atmosphere scattering model using a single image. Based on atmosphere scattering model, it simplifies the atmospheric scattering model from the perspective of fog formation and obtains new dehazing model. Then, it estimates the atmosphere light value, and it estimates the transmission by using the uncorrelation principle. Finally, it uses normalization method to adjust the transmission value, and takes into the new simplified model to get the dehazing image. In the experiments, the algorithm has a good effect on restoring the clear image’s contents and preserving the image’s true colors.
