Embodiment

[0063] Usually, the watermark occupies a small proportion of the picture, and often appears in non-key areas of the picture, such as the bottom (such as the lower left corner or the lower right corner) or the top (such as the upper left corner or the upper right corner) of the picture, etc. Such as figure 1 As shown, a picture containing a watermark is given, where the watermark is located in the upper right corner of the picture. The above-mentioned watermark recognition has brought great difficulties, so that the accuracy of watermark recognition is not high. Since the video can be understood as being composed of at least two video frames, and each video frame can be regarded as a picture, therefore, the picture described here can be a static picture, or a dynamic picture, or a picture in the video. video frame.

[0064] Regarding the recognition of the video watermark, the recognition of the so-called video watermark refers to determining whether the video contains a wate...

Abstract

The invention discloses a video watermark identification method and device, equipment and a storage medium. The method comprises the following steps: dividing a video frame in a video into two or morethan two image blocks to obtain an image sequence of each video frame; Inputting the image sequence of each video frame into a target detection model to obtain a classification result of each image block, and obtaining a video feature vector according to the classification result of each image block; And inputting the video feature vector into a watermark recognition model, and if the obtained watermark recognition probability is greater than or equal to a probability threshold, determining that the video contains the watermark. According to the embodiment of the invention, each image block is input into the target detection model; a watermark identification result of each video frame is obtained; According to the video watermark identification method and device, the watermark identification result of each video frame is input into the watermark identification model to obtain the watermark identification result of the video, and due to the fact that the watermark identification resultof each video frame is utilized, when the watermark position is not fixed, whether the video contains the watermark can still be accurately identified, and the identification precision of the video watermark is improved.

Description

technical field [0001] Embodiments of the present invention relate to identification technologies, and in particular to a video watermark identification method, device, equipment, and storage medium. Background technique [0002] Watermark is an important symbol of copyright protection. With the gradual improvement of users' copyright awareness, various watermarks have also been widely used. Exemplarily, if the watermark is embedded in the video, since the video can be understood as being composed of at least two video frames, each video frame can be regarded as a picture, so embedding the watermark in the video can be understood as embedding the watermark into each in the picture. [0003] Due to the widespread use of watermarks, the recognition of watermarks has also become a research direction. However, since the watermark usually occupies a small proportion of the picture, and often appears in a non-critical area of ​​the picture, such as the bottom (such as the lower ...
