Abstract: Embodiments of this application disclose a video data processing method and apparatus, and a storage medium. The method includes determining, in response to a trigger operation on a target video, a target pixel in a key video frame, and obtaining multimedia information associated with the target pixel, the key video frame being a video frame in which the trigger operation is located, and the target pixel corresponding to the trigger operation in the key video frame; identifying a trajectory obtaining request corresponding to the target pixel based on location information of the target pixel; obtaining target trajectory information associated with the location information of the target pixel, the target trajectory information comprising location information of the target pixel in a next video frame following the key video frame; and displaying the multimedia information based on the location information of the target pixel in the next video frame.

Abstract: This disclosure provides a method for embedding information into a video, a computer device, and a storage medium. The method includes: constructing a model conforming to a pixel distribution characteristic of the first embedding region; controlling update of the model based on a subsequent to-be-processed frame of the reference frame; identifying a background and a foreground of a second embedding region in the to-be-processed frame based on the model; generating a template used for occluding the background and exposing the foreground; applying the template to to-be-embedded information to generate an updated to-be-embedded information by occluding region of the to-be-embedded information corresponding to the foreground; and overlaying the second embedding region with the updated to-be-embedded information, so that the foreground of the second embedding region is devoid of occlusion by the overlaid to-be-embedded information.

Abstract: The present disclosure provides an image processing method and apparatus, an electronic device, and a computer-readable storage medium. The method includes: placing 3D model on a target plane of a first frame of the video, a plurality of feature points of a model surface of the 3D model falling on the target plane; determining a pose of a camera coordinate system of the first frame of the video relative to a world coordinate system; for a jth frame: determining pixel coordinates of the plurality of feature points of the model surface on the jth frame of the video; determining, a pose of a camera coordinate system of the jth frame of the video relative to a world coordinate system; and replacing the 3D model with a target model and placing the target model on the world coordinate system to generate, according to the pose of the camera coordinate system of each frame of the video relative to the world coordinate system, a target video comprising the target model.

Abstract: Embodiments of the present disclosure disclose an image processing method and apparatus. The method may include obtaining a harmonized image. The harmonized image may be harmonized with a promotional content image. The method may further include performing context feature extraction on the harmonized image to obtain context feature information of the harmonized image and extracting multi-level semantic information of an object in the harmonized image based on the context feature information. The method may further include performing image reconstruction based on the context feature information and the multi-level semantic information to obtain a reconstructed image. This solution can improve an image harmonization effect.
