Embodiment 1

[0043] figure 1 It is a flow chart of a video watermark removal method provided by Embodiment 1 of the present invention. This embodiment of the present invention is applicable to the situation of removing watermark in video data. The method can be executed by a video watermark removal device, which can be implemented by software and / or hardware, and integrated in the device performing the method, specifically, such as figure 1 As shown, the method may include the following steps:

[0044] S101. Extract multiple frames of image data from video data.

[0045] In the embodiment of the present invention, the video data can be short video data, longer video data, or gif animation, and the format of the video data can be rm, rmvb, mpeg, mov, mtv, avi, flv, etc. Format.

[0046] In practical applications, the video data can be obtained through the short video shooting APP to perform the video shooting operation, or the video data can be obtained when the live broadcast APP perfor...

Embodiment 2

[0057] Figure 2A It is a flowchart of a video watermark removal method provided by Embodiment 2 of the present invention. The embodiment of the present invention is optimized on the basis of the foregoing Embodiment 1. Specifically, as Figure 2A As shown, the method may include the following steps:

[0058] S201. Extract multiple frames of image data from video data.

[0059] S202. For each frame of image data, detect a specified type of watermark in the image data.

[0060] In the embodiment of the present invention, the specified type of watermark is the watermark that needs to be removed from the image data. After the watermark detection algorithm detects the image data, the detection result can be obtained. The detection result includes the watermark type, confidence and position of the watermark, Wherein, the watermark type may be the identification of the copyright party adding the watermark, the confidence level may be the degree of confidence that a watermark belon...

Embodiment 3

[0082] image 3 The flow chart of a video watermark removal method provided by the third embodiment of the present invention, the embodiment of the present invention is applicable to the situation of removing the watermark in the video data, the method can be executed by the video watermark removal device, and the device can use software and / or hardware, and integrated in the device performing the method, specifically, such as image 3 As shown, the method may include the following steps:

[0083] S301. When decoding video data, sample the decoded video data at a preset sampling rate to obtain multi-frame sparse image data of the video data.

[0084] Specifically, the preset sampling rate can be determined according to the frame rate of the video data. For example, if the video frame rate is 30 frames per second, one frame of decoded image data can be sampled every second when the video data is decoded, and the sampled The image data is sparse image data. Of course, it is al...

Abstract

The embodiment of the invention discloses a video watermark removing method, a video data publishing method and related devices. The video watermark removing method comprises the following steps: extracting multiple frames of image data from video data; detecting watermarks in the image data to obtain a plurality of initial watermark positions; determining the position belonging to the same watermark according to the plurality of initial watermark positions as a target watermark position; and removing the watermark in the target watermark position. According to the embodiment of the invention,the target watermark position belonging to the same watermark is determined according to the initial watermark position; wherein the target watermark position can include the initial watermark position of the watermark in each frame of image data; jittering of the detected initial watermark position is avoided. The problem that the watermarks in the video data cannot be completely removed due tothe fact that the detected initial watermark position deviates from the real position is solved, the watermarks in the clean video data can be removed after the watermarks of each frame of image dataare removed based on the target watermark position, and the video data watching experience of a user is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image processing, and in particular, to a method for removing a video watermark, a method for distributing video data, a device for removing a video watermark, a device for distributing video data, a device, and a storage medium. Background technique [0002] Adding watermarks to digital products is one of the ways to protect copyrights. With the gradual strengthening of copyright protection awareness, various watermarks are increasingly added to videos. [0003] For multimedia data, such as video data, in order to protect copyright, a watermark is usually added at a fixed position in the video data, so that the watermark is displayed at a fixed position on the video playback interface. However, in order not to affect the user watching the video, it is necessary to remove the watermark in the video data before the video data is released. Before removing the watermark, first detec...
