Fast algorithm for dark channel prior
Electronics Letters, 2014 A fast algorithm to calculate the dark channel prior (DCP) with the complexity constant for window size and linear for image size is presented. The strategy followed is that of ‘trade space for time’, and a data structure is developed, called the partitioned minimal table (PAMT), to orderly store the local minima of four partitions of every non ...

Pyramid Fusion Dark Channel Prior for Single Image Dehazing
CoRR, 2021 In this paper, we propose the pyramid fusion dark channel prior (PF-DCP) for single image dehazing. Based on the well-known Dark Channel Prior (DCP), we introduce an easy yet effective approach PF-DCP by employing the DCP algorithm at a pyramid of multi-scale images to alleviate the problem of patch size selection.

l2‐norm‐based prior for haze‐removal from single image
IET Computer Vision, 2016 Climatic and atmospheric phenomena – such as haze, fog and smoke – may lead to deterioration of quality and poor scenic clarity of outdoor images. In computer graphics, the authors can model these images as a linear combination of scene radiance, medium ...

Image Dehazing Algorithm Using Improved Dark Channel Prior and Strategic Fusion [PDF]
Jisuanji gongcheng, 2023 To address the problems of halo effect, color distortion, and poor treatment of sky regions in the Dark Channel Prior(DCP) algorithm for image dehazing, a novel image dehazing algorithm using an improved DCP and strategic fusion is proposed. Based on the

Image Dehazing in Disproportionate Haze Distributions
IEEE Access, 2021 Haze removal techniques employed to increase the visibility level of an image play an important role in many vision-based systems. Several traditional dark channel prior-based methods have been proposed to remove haze formation and thereby enhance the ...
