Abstract

The invention discloses an image enhancement method, apparatus and device, and a storage medium. The method comprises the steps of obtaining an original image to be subjected to image enhancement; for each pixel point in the original image, determining a contrast gain coefficient and a floating correction coefficient corresponding to the pixel point according to a plurality of pixel values in a preset pixel area taking the pixel point as a center; reducing or increasing the contrast gain coefficient corresponding to the pixel point by using the floating correction coefficient based on the corresponding texture condition of the pixel point in the original image to obtain a corrected target contrast gain coefficient; according to the method, each pixel point in the original image is enhanced based on the target contrast gain coefficient, the enhanced target image is acquired, and contrast enhancement or suppression is performed in a targeted manner according to the corresponding texture condition of the pixel point in the original image, so that the image looks clearer and more natural.

Description

technical field [0001] The present disclosure generally relates to the field of image processing, specifically relates to the technical field of image enhancement, and in particular relates to an image enhancement method, device, device and storage medium. Background technique [0002] Image contrast enhancement has important applications in many occasions, such as in the field of ISP (Image Signal Processing, Image Signal Processing) image imaging, because in many scenes, the contrast is low and there is no layering. Simply increasing the contrast can easily amplify the noise in the flat area, affecting the reading effect of the picture. Contents of the invention [0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide an image enhancement method, device, device and storage medium, which can perform contrast enhancement or suppression in a targeted manner according to the texture corresponding to pixels in the original ima...
