Title:
VIDEO SUPER-RESOLUTION NETWORK, AND VIDEO SUPER-RESOLUTION, ENCODING AND DECODING PROCESSING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/000179
Kind Code:
A1
Abstract:
A video super-resolution network, and a video super-resolution, encoding and decoding processing method and device. The video super-resolution network extracts shallow features and deep features of a low-resolution video frame sequence on the basis of 3D convolution, and reconstructs a video frame sequence of higher resolution. A discriminator network of the video super-resolution network uses two branches to respectively determine detail features and motion information features. Super-resolution of video frames in a video compression process can enhance image quality. Decoded super-resolution processing can also be combined with uncoded downsampling processing so as to transmit and restore low-bit rate images.
