Abstract

The invention provides an image restoration method and device based on visual selection fusion, equipment and a medium. The method comprises the steps: obtaining the threshold feature information of sky region segmentation of a foggy image through a statistical model, and carrying out the segmentation of a sky region of the image according to the threshold feature information, and obtaining the effective range of a global atmospheric background light value; obtaining an initial transmissivity image of the foggy day image, and optimizing the transmissivity image by using an adaptive boundary limitation L0 gradient minimization filtering method; within the effective range of the global atmospheric background light value, inputting the optimized transmissivity image into a dark primary colortheoretical model to obtain a plurality of restored initial defogged images; and constructing a method based on visual selection to select a defogged image suitable for participating in fusion from each initial defogged image, and fusing the selected defogged images by using an image fusion method based on a YCbCr color space to obtain a final fog-free image. Through the technical scheme of the invention, the restoration quality of the foggy image can be stabilized.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image restoration method, device, equipment and medium based on visual selection fusion. Background technique [0002] At present, the monitoring system used in road traffic is mainly applicable in a better unobstructed natural environment, but when encountering bad weather (such as fog), the images collected by the monitoring system camera will be blocked, resulting in road monitoring information There will be losses. Therefore, it is of great significance to better monitor road information in various natural environments. [0003] The current foggy image restoration method based on the dark channel theory generally uses the method of directly estimating the atmospheric background light to obtain the value of the global atmospheric background light, and performs a simple smoothing operation on the transmittance image, and then uses the dark channel model to ...
