Abstract

The invention relates to the technical field of image processing, in particular to an image enhancement method and device and electronic equipment. The method comprises the steps of obtaining a to-be-processed image corresponding to an original image, and extracting color information and saturation information of the original image; inputting the to-be-processed image into a brightness enhancementmodel to obtain enhanced brightness information; and fusing the color information, the saturation information and the enhanced brightness information, and determining the enhanced image to be processed; taking the to-be-processed image as the input of the brightness enhancement model, outputting the enhanced brightness information, fusing the enhanced brightness information with the color information and saturation information of the original image, so the obtained enhanced to-be-processed image can keep the color information and saturation information of the to-be-processed image unchanged;only the brightness information is enhanced, so that the color cast problem of the enhanced image is effectively solved.

Description

technical field

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

[0002] Images under low light conditions or backlight conditions often have problems such as low brightness, high noise, and poor contrast, which will affect people's perception of the image subjectively, and will also affect the follow-up at the pixel level of the image. Related tasks, such as license plate recognition under video surveillance at night, 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-illumination image enhancement methods has important practical significance and value.
