Abstract: Embodiments of this application provide a watermark embedding method applicable to a three-dimensional (3D) field. By combining vertex data of an original 3D model and vertex data of a 3D watermark, and combining material data of the original 3D model and material data of the 3D watermark, the original 3D model and the 3D watermark can be synthesized into a 3D model. In addition, before and after watermark embedding, an appearance of the original 3D model can remain unchanged. This avoids impact of watermark embedding on the appearance and use value of the 3D model, and ensures a display effect of the 3D model. Further, a function of encrypting the embedded 3D watermark may be implemented, and the 3D watermark cannot be easily removed or modified. This can effectively ensure the copyright of the original 3D model, and better promote a digital asset such as the 3D model.

Abstract: A video switching method includes a target object being selected. A similarity of the target object between a first image frame and a second image frame is calculated to obtain a similarity value, where the first image frame is from a first video, and the second image frame is from a second video; to-be-switched image frames are obtained, where the to-be-switched image frames include the first image frame and the second image frame with the similarity value greater than or equal to a preset threshold; and the first image frame of the first video is switched to the second image frame of the second video or the second image frame of the second video is switched to the first image frame of the first video based on the to-be-switched image frames.

Abstract: The method includes: after obtaining an image of a to-be-operated device by using a target application, the electronic device may send the image of the to-be-operated device to a server corresponding to the target application. Then, the server may obtain an operation model of the to-be-operated device based on the image of the to-be-operated device, and the server sends the operation model of the to-be-operated device to the electronic device. Next, the electronic device may display a user operation interface corresponding to the operation model, and the user may perform an operation on the user operation interface. The electronic device sends an operation event corresponding to the second operation of the user to the server, and the server processes the operation event corresponding to the second operation.
