Abstract

A far and near scene fusion defogging algorithm based on the prior of dark-light channel is proposed to solve the problem that traditional dark channel is not suitable for large sky area and it is easy to cause the distortion of dehazed image. Firstly

an improved two-dimensional Otsu image segmentation algorithm is utilized to mix the dark channels in the close and distant areas

and the adaptive adjustment parameters of the mixed dark channels are calculated based on the optimal objective quality evaluation index for the close and distant areas. Secondly

aiming at the problem that atmospheric light is not uniform and constant in real physical scenes

a dark-light channel fusion model is established to calculate the atmospheric light map. Furthermore

in order to improve processing speed

the grayscale image corresponding to the original image is selected as a guide image to refine the transmittance image without reducing restoration quality. Finally

the brightness/colour compensation model based on visual perception is used for image correction to improve the contrast and colour saturation of the restored image. Experimental results show that the proposed algorithm achieves the best results from both subjective and objective perspectives

in which the objective index PSNR is 24.04% higher than that of He's algorithm on average. It is concluded that the image recovered by the proposed algorithm is clearer

with more obvious details and structure

and is more suitable for human eyes to observe

which verifies the effectiveness of the algorithm.
