A Review on Different Image De-hazing Methods

Abstract

This paper is written to present a review on the different haze removal techniques. Image de-hazing is the most important field of research in image processing and analysis. The process of de-hazing is important to make human understanding easier in low visibility. Haze is a state of poor air quality characterized by a pale scent appearance of atmosphere and reduces visibility. It is caused by high concentration of air pollutants suspended in the atmosphere that scatter and absorb sunlight. Because of this, the picture gets whitened and its contrast is reduced. The de-hazing techniques are very much in use in the field of numerous applications in the field of computer vision such as video surveillance and detection of object. The thorough purpose of this paper is to delve different procedures of efficaciously expel haze from any image and checks the drawbacks of the existing methods.
