Visibility Improvement in Foggy Images using POSHE Algorithm
نویسنده
چکیده
Bad weather, such as fog and haze, can significantly degrade the visibility of a scene. Optically, this is due to the substantial presence of particles in the atmosphere that absorb and scatter light. In order to deal with the information of fog image, a method for improving image definition based on image segmentation and image improvement technologies is presented. First of all, in accordance with the characteristics of the grayscale distribution of image, the method finds the non-sky region using regional growth method, and then only in this region POSHE algorithm is used to improve the definition of scene in fog image. The experimental results show that the method can effectively improve the image of degradation in fog and improve image definition. Keywords-Image segmentation, regional growth, POSHE algorithm, image degradation, image definition.

Referenceless perceptual fog density prediction model
We propose a perceptual fog density prediction model based on natural scene statistics (NSS) and “fog aware” statistical features, which can predict the visibility in a foggy scene from a single image without reference to a corresponding fogless image, without side geographical camera information, without training on human-rated judgments, and without dependency on salient objects such as lane ...

Low visibility on expressways caused by heavy fog and haze is a main reason for traffic accidents. Real-time estimation of atmospheric visibility is an effective way to reduce traffic accident rates. With the development of computer technology, estimating atmospheric visibility via computer vision becomes a research focus. However, the estimation accuracy should be enhanced since fog and haze a...

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...

Because of light scattered by the suspended particles in the atmosphere, photographs taken in the foggy day look gray and lack of visibility. In order to unveil the clear image’s structures and colors, we propose a image defogging algorithm of single color image based on wavelet transform and histogram equalization. Firstly, using histogram equalization to enhancement image, then to nonlinear e...

Images captured in foggy weather conditions often suffer from poor visibility, which will create a lot of impacts on the outdoor computer vision systems, such as video surveillance, intelligent transportation assistance system, remote sensing space cameras and so on. In this paper, we propose a new transmission estimated method to improve the visibility of single input image (with fog or haze),...
