Title:
VIDEO SUPER-RESOLUTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/174416
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of image processing. Provided in the embodiments of the present disclosure are a video super-resolution method and apparatus. The method comprises: separately decomposing into N image blocks the t-th image frame of a video to be subjected to super-resolution and a neighborhood image frame of the t-th image frame; generating N image block sequences, the image blocks in each image block sequence being located at the same position of different image frames; computing motion parameters of each image block sequence, the motion parameters of the image block sequence comprising motion parameters between the image blocks of the adjacent image frames in the image block sequence; according to the motion parameters of each image block sequence, determining a super-resolution network model corresponding to the image block sequence; using the corresponding super-resolution network model to perform super-resolution on the image block of the t-th image frame in each image block sequence, so as to obtain super-resolution image blocks of the t-th image frame; and according to the super-resolution image blocks of the t-th image frame, generating a super-resolution image frame of the t-th image frame.
