Abstract

The invention relates to the technical field of image processing, specific equipment and an image enhancement method, device and electronic equipment. The method includes acquiring a to-be-processed image corresponding to an original image and extracting color information and saturation information of the original image; Input into the brightness enhancement model to obtain enhanced brightness information; fuse the color information, the saturation information and the enhanced brightness information to determine the enhanced image to be processed. The image to be processed is used as the input of the brightness enhancement model, and the output is enhanced brightness information, and the enhanced brightness information is fused with the color information and saturation information of the original image, and the obtained enhanced image to be processed can keep The color information and saturation information of the image to be processed remain unchanged, and only the brightness information is enhanced, thereby effectively solving the color cast problem of the enhanced image.

Description

technical field

[0001] The present invention relates to the technical field of image processing, in particular to an image enhancement method, device and electronic device. Background technique

[0002] Images often have problems such as low brightness, high noise, and poor contrast in low lighting environments or backlight conditions, which subjectively affect people's perception of the image, and also affect the subsequent image pixel level. Related tasks, such as license plate recognition under night video surveillance, face recognition under backlight conditions, etc. Image enhancement technology can reduce the noise in the image, improve the contrast between the object and the background, and improve the visual effect of the image, which is also the basis for subsequent related recognition tasks. Therefore, the research on low-light image enhancement methods has important practical significance and value.

[0003] The currently used image enhancement method is to acqu...
