Abstract

The invention relates to a video processing method and a video processing device, and the method comprises the steps of obtaining an input feature of a current moment for an image frame of each moment in a video based on the image frame of the current moment, hidden layer features of m moments before the current moment, and super-division features of n moments before the current moment; inputting the input feature of the current moment into a video super-resolution model to obtain a super-resolution feature of the current moment output by an output layer of the video super-resolution model and a hidden layer feature of the current moment output by a hidden layer of the video super-resolution model, wherein the hidden layer feature of the current moment is used for obtaining input features of m moments after the current moment; and obtaining a super-resolution image at the current moment based on the super-resolution feature at the current moment and the image frame at the current moment, wherein m is an integer greater than or equal to 1, n is an integer greater than or equal to 1, and m and n are not 1 at the same time.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and more specifically, to a video processing method and a video processing device. Background technique [0002] Low-resolution video transmission is a way to save costs and reduce bandwidth. Video super-resolution algorithms can cooperate with this transmission strategy to restore these low-resolution videos to high-resolution videos and then send them to users, thus improving the performance of video super-resolution algorithms. Performance is very necessary. [0003] In the related art, the video super-resolution algorithm may include an algorithm based on explicit motion compensation. Algorithms based on explicit motion compensation often use optical flow as the motion representation between video frames, but the estimation of optical flow is often inaccurate and time-consuming. Contents of the invention [0004] The present disclosure provides a video processing method and a v...
