Haze Removal System using Dark Channel Prior
International Journal for Research in Applied Science and Engineering Technology, 2021 Mostly in winter season, the Northern area of India is mostly affected due to heavy haze. The road traffic and air traffic is affected due to poor visibility. According to the survey of Ministry of Road Transport and Highways of India, the number of accident due to poor visibility increasing every year.

Single Image Dehazing using Extended Local Dark Channel Prior
Image and Vision Computing, 2022 Abstract Image dehazing is an important technique aimed at eliminating the haze in the atmosphere to enhance the image's visual quality. There are many applications where it has been used as a prepossessing step, such as in event detection. In recent years, the dark channel prior methodology has been recognised as an effective approach for ...

Adaptive Tolerance Dehazing Algorithm Based on Dark Channel Prior
Algorithms, 2020 The tolerance mechanism based on dark channel prior (DCP) of a single image dehazing algorithm is less effective when there are large areas of the bright region in the hazy image because it cannot obtain the tolerance adaptively according to the ...
