Abstract

The invention provides a video processing method and a video processing device. The video processing method comprises the following steps: acquiring a current frame of a low-resolution video at a current moment and an adjacent frame adjacent to the current frame; obtaining a difference image for the current frame based on the current frame and the adjacent frame; determining time attention information for the current frame according to the difference image, wherein the time attention information represents image feature information concerned by the current frame relative to the adjacent frame; obtaining super-resolution characteristics of the current frame according to the time attention information and the adjacent frame; and generating a high-resolution image of the current frame based on the super-resolution feature.

Description

technical field [0001] The present disclosure relates to the field of video processing, and in particular, to a video processing method and a video processing device for super-resolution. Background technique [0002] Video data in actual demand is mainly divided into single-frame images and video sequences. Depending on the input data, super-resolution (SR) can be subdivided into two directions: single-frame image super-resolution (SISR) and video super-resolution (VSR). The focus of SR algorithm design under different tasks is also different. The SISR algorithm is mainly a super-resolution method based on a single frame image, and its purpose is to use the self-similarity information and structural information of the image itself to generate the missing details from the low-resolution image to the high-resolution image; and the VSR algorithm is The extension method of SISR algorithm in time needs to consider both the self-similarity within the frame and the spatial-tempo...
