Abstract

The invention relates to a video processing method and device. The video processing method comprises the following steps: acquiring all video frames of a video; for each of the video frames, the following processing is performed: calculating a change image between a current video frame and an adjacent video frame, wherein the adjacent video frame is a video frame adjacent to the current video frame, calculating spatial attention information between the current video frame and the adjacent video frame based on the change image, obtaining the features for super-resolution of the current video frame based on spatial attention information between the current video frame and the adjacent video frame, and generating a high-resolution video frame for the current video frame based on the feature for super-resolution. According to the video processing method and device, the attention to the complementary region can be improved based on the spatial attention information, and the attention to the redundant region can be reduced so that the super-resolution performance is improved.

Description

technical field [0001] The present disclosure relates to the field of video technology. More specifically, the present disclosure relates to a video processing method and device. Background technique [0002] Super-resolution is a classic task in the field of computer vision. With the help of image prior knowledge and image self-similarity, it fills in the missing detail information from low-resolution to high-resolution changes to generate corresponding high-resolution images. Thanks to the emergence of deep learning methods, convolutional neural networks have achieved good performance in super-resolution tasks by extracting underlying texture information to establish a low-resolution to high-resolution mapping relationship. In recent years, with the development of video technology, video super-resolution has become a hot research topic. Compared with image super-resolution, video contains rich temporal complementary information, which can more robustly deal with the infl...
