Title:
IMAGE RESTORATION METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/130650
Kind Code:
A1
Abstract:
An image restoration method and apparatus, an electronic device, and a storage medium. The method comprises: acquiring an original low-light image to be restored; acquiring a pre-trained image processing model (S11); and inputting the original low-light image into the image processing model, such that an optical feature extraction network in the image processing model extracts an illumination feature from the original low-light image, and an image feature extraction network extracts a target image feature from the original low-light image, and generating a target bright image on the basis of the illumination feature and the target image feature (S13). An optical feature extraction network and an image feature extraction network are respectively used to process an image feature of an original low-light image, so as to obtain an illumination feature and a target image feature, and the illumination feature is then fused with the target image feature for image restoration, such that low-light enhancement is performed on a low-light image by using a model to obtain a bright image, and there is no need to perform image restoration by using a low-light enhancement model and a super-resolution model, respectively.
