Outdoor Images captured under inclement weather conditions are degraded by various atmospheric particles, which vary in size and concentration. To restore the visibility of the degraded images, various state-of-the-art algorithms were developed for the past decade. In this paper, an overview of various research works carried over the past decade related to static weather conditions like Haze, fog and dynamic weather conditions like rain are investigated. Also, the merits and demerits of each algorithm along with the challenges in this area are focused. © 2006-2016 Asian Research Publishing Network (ARPN).
