What is it about?
After studying the aviation problems in Iraq, on one hand, and because Iraq has various weather characteristics due to its different terrains (i.e. mountains, plain fields, and deserts). We discussed these problems with pilots and aviation specialists, and came to the conclusion that the main offset faced is vision deficiency is foggy and dusty weather. Thus, the Iraqi aviation reconnaissance system was developed to overcome this hurdle by implementing instant image rendering by developing this technology to remove fog and such hazy particles utilizing dark channel prior (DCP) image processing algorithm since this method is highly capable of resolving the fog/haze weather condition problems. The DCP algorithm suggested showed a reasonable enhancement of the images with foggy, hazy, and dusty conditions when the Unmanned Aerial Vehicle (UAV) was used to capture images at various altitudes corresponding to the same height most helicopters and reconnaissance UAVs fly at. Our main contribution is based on the evaluation of optimal values of DCP parameters/metrics to the hazy images and performs UAV image dehazing and enhancement.

Why is it important?
The presence of haze reduces the perception of the Aerial imagery observed by the captured image in the UAV. Such deterioration affects computer vision systems' efficiency in aerial vehicle applications, including video monitoring, automatic vehicle navigating, and remote sensing. Light dispersion is caused by suspended objects, just like droplets of water or smog that can reduce the visibility in hazy environments. The degree of visibility losses depends upon the intensity and range among view objects and the observational location of the suspended particles in that environment. During the past years, studies have concentrated on creating effective computational methods to eliminate the effects of haze in aerial photogrammetry of the exterior surroundings. For example, the processing of many views captured during various hazy circumstances is an algorithm on which the research is based
