Abstract: Unmanned Aerial System (UAS) have become very popular these days as they are replacing human effort to carry out operations in certain areas where human beings cannot have access. They have made their way through the military as well as civilian sectors. They are also of low cost and easy to operate. During Low visibility conditions, when the UAV is flying out side of Line Of Sight (LOS), we will make use of First Person View (FPV). During such exercise images may affect with haze, blur & noise. Dark Channel Prior method is used to remove haze from a single input image; Blurred images are handled by deploying a Wiener filter.
 
Keywords: UAS, LOS, FPV, Low visibility, Haze, Blur, Dark Channel Prior, Wiener filter.
