Images plays a very important role in human being’s life. They are very useful in all the problems we came across day by day. Such as, satellite images are used for traffic analysis or in developed cities traffic analysis is also done through the CCTV cameras. But images which are captured under bad weather conditions suffer low contrast so as their quality also degrade with the changes in atmo...

Bad weather conditions such as fog, haze, and dust often reduce the performance of outdoor cameras. To improve the effectiveness of surveillance and in-vehicle cameras under such conditions, we propose a method based on a dark channel prior for quickly defogging images. It first estimates the intensity of the atmospheric light by searching the sky area in the foggy image. Then it estimates the ...

In order to improve the image quality in fog, this paper presents a fog-image enhancement algorithm based on adaptive guided image filter Retinex theory. Firstly convert the image from the RGB color space to the HSV color space, Then, the luminance image is estimated by adaptive guided image filter, the saturation image is linearly stretched. Finally, the image is transformed back from HSV colo...
