Embodiment 1

[0043] figure 1 It is a flow chart of a method for superimposing a video watermark provided in Embodiment 1 of the present invention, and the method includes the following steps:

[0044] Step S11: Extracting frame data of the video, performing conversion processing of the preset encoding format on the frame data, and performing processing of arranging the preset data format to obtain the converted frame data.

[0045] In the embodiment of the present invention, the purpose of superimposing the watermark on the video is to indicate the source of the video and prevent others from using the video for other activities or commercial use at will, thereby causing legal trouble or economic loss to the video author. When the video superimposition watermark operation needs to be performed in the computer equipment, the frame data that needs to be superimposed with the watermark is first extracted. Watermark superimposition processing is performed on each frame of the video, or when th...

Embodiment 2

[0057] image 3 It is a flow chart of image synthesis with preset watermark data provided by Embodiment 2 of the present invention, and the method includes the following steps:

[0058] Step S31: According to the image size of the converted frame data and the preset watermark data, and the boundary parameters of the preset watermark data, calculate the time when the preset watermark is synthesized in the converted frame data coordinate.

[0059] In the embodiment of the present invention, before synthesizing the preset watermark data into the converted frame data, it is necessary to add and calculate the coordinates at which the watermark is synthesized on the converted frame data. Wherein, the boundary parameters of the preset watermark data include the distance between the edge of the watermark and the boundary of the video, for example, the distance between the left edge of the watermark and the left boundary of the video is 10 pixels, and the pixels between other edges an...

Embodiment 3

[0075] Figure 5 It is a flow chart of a video superimposing watermarking device provided by Embodiment 3 of the present invention.

[0076] The video superimposed watermarking device 500 includes:

[0077] The frame data conversion module 510 is used to extract the frame data of the video, and perform preset encoding format conversion processing on the frame data, and perform preset data format arrangement processing to obtain converted frame data;

[0078] An image synthesis module 520, configured to use the converted frame data and preset watermark data to perform image synthesis to obtain synthesized frame data;

[0079] The inverse conversion module 530 is configured to perform inverse processing of the preset encoding format conversion on the synthesized frame data, and inverse processing of the arrangement of the preset data format to generate watermarked frame data;

[0080] A watermark frame replacement module 540, configured to use the watermarked frame data to rep...

Abstract

The invention provides a video watermark overlapping method and device, computer equipment and a computer storage medium, and the method comprises the steps of extracting the frame data of a video, carrying out the preset coding format conversion processing of the frame data, and carrying out the preset data format arrangement processing, and obtaining the converted frame data; performing image synthesis by using the converted frame data and the watermark data in the preset data format to obtain synthesized frame data; and performing inverse processing of preset coding format conversion and inverse processing of preset data format arrangement on the synthesized frame data to generate frame data with watermarks. According to the video watermark overlapping method, the frame data is subjected to the preset coding format conversion processing and the data format arrangement processing, and then the watermark superimposing processing is performed, so that the video watermark superimposing efficiency can be improved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a video superimposed watermark method, device, computer equipment and computer storage medium. Background technique [0002] At present, in order to prevent the video from being stolen by others at will, the copyright owner of the video generally adds a semi-transparent watermark on the specified position of the video. Adding watermark is an effective way to protect information security, realize anti-counterfeiting traceability and copyright protection without affecting the original effect of the video. [0003] In the existing watermarking method, generally adopt opencv (Open Source Computer Vision Library, open source computer vision library) to realize the superimposition of video and watermark image. However, the speed of using opencv is very slow, and the efficiency of adding watermarks is relatively low. Contents of the invention [0004] In view of the above pro...
