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: A quantum circuit includes: a qubit, a resonant cavity, and a feeder, the resonant cavity being coupled to the qubit, and the feeder being coupled to the qubit. The feeder is configured to feed an initialization signal to the qubit, the initialization signal being a modulation signal used for causing a frequency of the qubit to generate a vibration. The vibration causes an equivalent state exchange to occur between the qubit and the resonant cavity, and an excited state of the qubit is initialized to a ground state by using the resonant cavity.
