Title:
IMAGE RECONSTRUCTION METHOD AND APPARATUS, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/155305
Kind Code:
A1
Abstract:
The embodiments of the present application belong to the technical field of image processing. Provided are an image reconstruction method and apparatus, and an electronic device and a storage medium. The method comprises: acquiring an original image; performing degradation processing on the original image using a preset image degradation model, and determining a target blur kernel that matches the original image; performing dimensionality change processing on the target blur kernel, so as to generate a degraded image; and inputting the original image and the degraded image into a pre-trained image restoration model for processing, so as to obtain a reconstructed image, wherein the resolution of the reconstructed image is higher than the resolution of the original image. By means of the embodiments of the present application, the effect of an unknown blur kernel on image reconstruction can be reduced, and the reconstruction of an image having any blur kernel is realized, thereby improving the image quality of a reconstructed image.
