Abstract

The invention relates to an image processing method and apparatus, a computer device and a computer readable storage medium. The method comprises the steps of shooting a same scene through a black-white camera to obtain multiple black-white images, and shooting the same scene through a color camera to obtain color images; obtaining maximum brightness values corresponding to the black-white images, performing weighting processing on the maximum brightness values corresponding to the black-white images to obtain target brightness values, and taking the target brightness values as airglow values; obtaining original transmissivity according to the airglow values; and performing defogging processing on the color images according to the airglow values and the original transmissivity. The calculation amount of the obtained airglow values is small and the defogging efficiency is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an image processing method, device, computer equipment and computer-readable storage medium. Background technique [0002] With the rapid development of electronic technology, various electronic devices are equipped with cameras, through which users can record the scenery they see or take selfies anytime and anywhere. Affected by the environment, there is often fog in the captured image, which reduces the quality of the image. The traditional method of dehazing obtains the atmospheric light value, the calculation is complicated, and the dehazing efficiency is low. Contents of the invention [0003] Embodiments of the present invention provide an image processing method, device, computer equipment, and computer-readable storage medium, which can reduce calculation amount and improve defogging efficiency. [0004] An image processing method, comprising: [0005] Shoo...
