Single Image Dehazing Using Haze Veil Analysis and CLAHE

Abstract

Images of the outdoor scene appear hazy due to degradation occurred by atmospheric particles (water droplets, dust, etc.) while capturing the image.Hazing creates lots of problem in the areas of surveillance, tracking and navigation and other applications.Dehazing such images is desired in digital photography and computer vision.Thus, to remove it from an image, single image and multiple images defogging methods have been proposed in the literature.In this paper, we present a single image dehazing approach using haze veil analysis.Contrast limited histogram equalization (CLAHE) technique is used to improve the contrast of the image.The proposed method has been evaluated on different foggy/hazy images.The proposed system yielded better results in terms of preserving the finer details and the color quality of the images.
