Problems solved by technology

In the communication session, everyone at the listening end may turn around to talk. At this time, not all the people who turn around to talk show their faces. Not showing their faces means that they cannot be framed to select the active area of ​​the face, and then face recognition cannot be performed, resulting in At this time, the live video watched by the presenter is missing the label of the person who turned to talk

Abstract

The invention discloses a method and device for adding information to a video character, equipment and a storage medium. The method comprises the following steps that an identified image frame is extracted from a video to be processed, and the identified image frame comprises a human-shaped area corresponding to at least one person and person information added to the human-shaped area; taking an area with the same position as the human-shaped area in the identified image frame as a human-shaped area in the unidentified image frame; and associating the human shape area in the unidentified image frame with human information which is the same as the human shape area of the recognized image frame. According to the invention, in remote teaching or a remote conference, the character can be continuously marked when the front face of the character cannot be exposed, the adaptability of equipment is improved, human face monitoring does not need to be carried out on the character in a video for a long time, and the performance of hardware equipment is released.

Description

technical field [0001] The present invention relates to the technical field of image processing, and more specifically, to a method, device, device and storage medium for adding information to video characters. Background technique [0002] At present, AI technology is more and more applied in life, teaching, and enterprises, among which face detection and face recognition technologies are more and more used in automatic roll call. In remote conferences or remote teaching, the speaker can generally watch the live video of the listening terminal in real time. like figure 1 As shown, the person in the video can be identified by face recognition technology, and then a corresponding tag, such as a name, can be added to the person on the video. Through the name tags on the video, the speaker knows the names of the characters in the video, which is convenient for roll call and dialogue. [0003] However, in teleconferencing and distance teaching, there is generally a link of co...
