Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of this application.

[0038] For video repair, in essence, it is to perform super-resolution repair on each frame of the video, so as to achieve the purpose of overall repair of the video and enhance the effect of resolution. However, in the current application scenarios, videos are often generated by long-term recording, so the number of video frames contained in the video is relatively large, which leads to super-resolution processing of each video frame, and the amount of data proce...

Abstract

The invention discloses an ESRGAN-based video super-resolution restoration technology, device and equipment, and a storage medium. The method comprises the steps of obtaining a to-be-restored video; extracting a key frame in the to-be-restored video, and restoring an image of the key frame; grouping video frames in the to-be-restored video to generate frame groups, wherein the frame group comprises a key frame; sampling the repaired key frame in the frame group to generate a sample block; and repairing the to-be-repaired frame in the frame group through the sample block. According to the method, the data processing amount in the video restoration process is relatively reduced, so that the overall efficiency of video restoration is improved. In addition, the invention further provides a video restoration device and equipment and a storage medium, and the beneficial effects are the same as described above.

Description

technical field [0001] The present application relates to the field of video restoration, in particular to an ESRGAN-based video super-resolution restoration technology, device, equipment and storage medium. Background technique [0002] The current video repair technology mainly adopts super-resolution technology (Super-Resolution), which refers to reconstructing corresponding high-resolution images from observed low-resolution images, which is widely used in video surveillance, medical imaging, satellite images and other fields. It has important application value. [0003] For video repair, in essence, it is to perform super-resolution repair on each frame of the video, so as to achieve the purpose of overall repair of the video and enhance the effect of resolution. However, in the current application scenarios, videos are often generated by long-term recording, so the number of video frames contained in the video is relatively large, which leads to super-resolution proce...
