Estimation of the depth information
As the relationship among the scene depth d, the brightness v and the saturation s has been
modelled and the coefficients have been estimated, we can recover the depth map of the
given input hazy image according to Equation (5). In Figure 3, we show that the depth
maps d and the transmission maps t of the hazy images can be well recovered by the
proposed method. With the estimated depth map, the task of dehazing is no longer difficult.
