Abstract :
The visibility of outdoor images is reduced by the turbid medium of the atmosphere. The reduction of visibility is due to the substantial presence of particles in the atmosphere that scatters and absorbs light. The atmospheric scattering model is usually used to describe and restore the visibility in outdoor images. This model is mainly based on the depth of the scene and the skylight. In this research, we suggest new method to precisely estimate the skylight value. It is a fast method because it is based on linear calculation. In addition, it can be applied to different types of outdoor images.
