Enhancement of fog degraded images on the basis of histrogram classification

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 due to this captured images degrade significantly. This leads to accidents in air, on sea and on the road. This paper presents image enhancement methods for fog degraded images depending on the histogram based classification of the images. This methods does not require any environmental condition to be known in which image is captured or multiple images, it requires only single input image Here we first classify the given image into one of the four classifications (left, middle , right and right with peak) and based upon its class, we propose methods for the enhancement of its visibility.
