Abstract: Pictures caught in dim or hazy weather patterns can be genuinely debased by dissipating of climatic particles, which lessens the differentiation, changes the variety, and makes the object highlights challenging to recognize by human vision and by some outside PC vision frameworks. Accordingly picture dehazing is a main issue and has been broadly explored in the field of PC vision. The job of picture dehazing is to eliminate the impact of weather conditions factors to work on the visual impacts of the picture and give advantage to post-handling. This paper surveys the fundamental methods of picture dehazing that have been created throughout the last ten years. Initially, we creatively partition various methodologies into three classifications: picture improvement based strategies, picture combination based techniques and picture reclamation based strategies. All strategies are dissected whats more, relating subclassifications are acquainted concurring with standards and qualities. Different quality assessment techniques are then portrayed, arranged and examined exhaustively. At long last,research progress is summed up and future examination bearings are recommended. Key words: Image dehazing, reclamation, classification, quality assessment
