Title:
SUPER-RESOLUTION METHOD AND APPARATUS, TERMINAL DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/160980
Kind Code:
A1
Abstract:
A super-resolution method and apparatus, a terminal device, and a storage medium, relating to the technical field of deep learning, and capable of reducing the amount of computation. The super-resolution method comprises: inputting a low-resolution image to be processed into a trained classification and super-resolution network model for processing, and outputting to obtain a high-resolution image corresponding to the low-resolution image, wherein the classification and super-resolution network model comprises a classification model and multiple super-resolution network models having different complexity, and the process of processing the low-resolution image by the classification and super-resolution network model comprises: segmenting the low-resolution image into multiple subimages; for each subimage, determining the complexity of the subimage according to the classification model, inputting the subimage into the super-resolution network model corresponding to the complexity of the subimage among the multiple super-resolution network models for processing, and outputting to obtain a reconstructed image of the subimage; and stitching the reconstructed image of each subimage to obtain a high-resolution image.
