Abstract

The invention discloses an image defogging and denoising method, device and equipment, and a computer readable storage medium. The method comprises the steps of constructing an H-TVBH model accordingto a dark channel prior principle, an atmospheric scattering model and a TVBH model; obtaining an original image, and calculating the initial transmissivity and the atmospheric light value of the original image; and inputting the original image, the initial transmissivity and the atmospheric light value into an H-TVBH model, and solving the H-TVBH model to obtain a defogged and denoised image. According to the technical scheme, defogging and denoising processing on the original image is realized through the constructed H-TVBH model, so that a relatively good image processing effect is achieved; and due to the fact that rule items in the TVBH model can keep image edge details, the H-TVBH model obtained by combining the TVBH model can reserve the edge features of the original image when defogging and denoising processing is carried out on the original image, so that the processing effect of image defogging and denoising is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and more specifically, to an image defogging and denoising method, device, equipment, and computer-readable storage medium. Background technique [0002] When acquiring outdoor images under severe weather conditions (such as haze, etc.), the captured scene has a significant decrease in visibility, which is due to the interaction (scattering, absorption, and emission) of light with particles suspended in the atmosphere, resulting in image Images captured in adverse weather conditions require processing due to reduced contrast, washed out colors, and low saturation. [0003] At present, when processing images taken under severe weather conditions, only attention is paid to the defogging of the image, that is, only the image is defogged, and the noise in the image is not removed. Therefore, Then a better image processing effect cannot be achieved. [0004] To sum up, how to perf...
