Problems solved by technology
For videos of the same site and size, the position, shape, and color of the watermark are basically unchanged. The watermark of some videos will be difficult to identify because the video image changes little for a long time. The existing methods for identifying watermarks in videos are difficult to identify. Watermarks in videos with small video image changes
At the same time, the existing methods for identifying watermarks in videos usually need to calculate each pixel in each frame of the video file, which is less efficient

The invention discloses a method and device for recognizing a watermark in a video, electronic equipment and a computer readable storage medium. The method comprises the steps that at least one samplevideo file with the specific video height and width is selected from video files of a target station; watermarks are recognized out from the sample video files, and a watermark template correspondingto the video files with the specific video height and width of the target station area is constructed; and watermark recognition is conducted on a to-be-recognized video file with the specific videoheight and width of the target station according to the watermark template. According to the method, the watermark template corresponding to the video files with the specific video height and width ofthe target station is constructed and can be used for conducting watermark recognition on the to-be-recognized video file with the specific video height and width of the target station, the problem that in the prior art, the watermark in the video with the little video image change is difficult to recognize is solved, and the efficiency of recognizing the watermark in the video is improved.
Description
technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device, electronic equipment and computer-readable storage medium for identifying watermarks in videos. Background technique [0002] With the promotion of camera technology and the development of Internet technology, the application of video is more and more extensive. Different from the requirements of long videos on traffic and video quality, the short duration and simple production process of short videos make it flourish in the current environment. Many high-quality UGC (User Generate Content, user-generated content) and PGC (Professional Generate Content, professionally generated content) users create videos on a few video sites, which cannot spread high-quality videos well. [0003] The video aggregation platform with large traffic has hundreds of millions of users, which can integrate high-quality videos well, and bring more high-quality videos to mor...
