Image dehazing is a method to improve the images gained in poor weather conditions, for example, haze and dimness. Existing image dehazing strategies are principally in view of dark channel prior. Since the dark channel isn`t sensible for sky regions, a sky division and area wised medium transmission based image dehazing strategy is proposed in this paper. Right off the bat, sky regions are divided by quad-tree part based component pixels location. At that point, a medium transmission estimation strategy for sky regions is proposed in view of shading trademark perception of sky regions. The medium transmission is then separated by an edge saving guided channel. At long last, in light of the evaluated medium transmission, the hazed images are reestablished. Exploratory outcomes show that the execution of the proposed strategy is superior to that of existing techniques. The reestablished image is more regular, particularly in the sky regions.
