Current image processing application captures degraded contrast with error prone images in fog condition Single-Image algorithms used for fog condition of daytime. It is bases on mathematical model to compute atmospheric veil by considering the variation in fog density with distance. Objects at greater distance are not visible in fog. Density of Fog is low and has characteristic of nonlinear increase with distance. Quantifiable and approximate calculations are done on Images. By using this process, it is feasible for reconstruction of fog-free image. And it proves that the mathematical model is one solution for contrast rebuilding in homogeneous or heterogeneous conditions.
