Embodiment 1

[0069] Figure 1a A flowchart of a method for adding video special effects provided in Embodiment 1 of the present disclosure. This embodiment can be applied to the case of adding video special effects to a video. The method can be executed by a video special effect adding device, and the device can use software and and / or hardware, the apparatus may be configured in a terminal device, such as a typical computer. like Figure 1a As shown, the method specifically includes the following steps:

[0070] S110: Acquire at least one image frame in the video, and identify at least one target human body joint point of the user in the image frame.

[0071] In general, a video is formed by a series of static image frames that are shown in rapid succession. Thus, the video can be split into a series of image frames, and the image frames can be edited, so as to realize the editing operation of the video. When there are multiple users in the image frame, one of the users can be selected ...

Embodiment 2

[0099] Figure 2a This is a flowchart of a method for adding special effects to a video provided in Embodiment 2 of the present disclosure. This embodiment is embodied on the basis of each optional solution in the foregoing embodiment. In this embodiment, acquiring at least one image frame in the video is embodied as: acquiring at least one image frame in the video in real time during the video recording process. At the same time, adding the video special effect matching the joint position condition at the video position associated with the target image frame in the video is embodied as: using the video position of the target image frame as the starting point for adding special effects ; According to the special effect duration of the video special effect matching the video special effect condition, starting from the starting point of adding the special effect, add the video special effect in the image frame matching the special effect duration in the video.

Embodiment 3

[0130] image 3 This is a schematic structural diagram of a device for adding video special effects provided by an embodiment of the present disclosure, and this embodiment can be applied to a situation in which video special effects are added to a video. The apparatus may be implemented in software and / or hardware, and the apparatus may be configured in a terminal device. like image 3 As shown, the device may include: a target human body joint point identification module 310 , a joint position condition determination module 320 , a joint point motion state detection module 330 , a joint action condition determination module 340 and a video special effect adding module 350 .

[0131] The target human body joint point identification module 310 is configured to acquire at least one image frame in the video, and identify at least one target human body joint point of the user in the image frame;

[0132] The joint position condition judging module 320 is configured to obtain th...

Abstract

The disclosure discloses a video special effect adding method and device, terminal equipment and a storage medium. The method includes: acquiring at least one image frame in a video, and identifying at least one target human body joint point of the user in the image frame; if it is determined that a target human body joint point identified in a target image frame meets a joint position condition,acquiring at least two consecutive image frames before the target image frame; identifying the target human body joint point according to the at least two consecutive image frames, and determining a motion state of the target human body joint point; if it is determined that the target human body joint point meets a joint motion condition, acquiring a video special effect matching with a video special effect condition; and adding the video special effect, which matches with the video special effect condition, at a video position which is in the video and is associated with the target image frame. The embodiment of the disclosure can improve scene diversification of video interaction applications.

Description

technical field [0001] The embodiments of the present disclosure relate to data technologies, and in particular, to a method, apparatus, terminal device, and storage medium for adding special effects to a video. Background technique [0002] With the development of communication technology and terminal equipment, various terminal equipment such as mobile phones and tablet computers have become an indispensable part of people's work and life, and with the increasing popularity of terminal equipment, video interactive applications have become a kind of The main channel of communication and entertainment. [0003] Currently, video interaction applications can recognize the user's face, and add a static image on the user's head (for example, adding a headgear to the hair) or add facial expressions to cover the user's face. This method of adding images is too limited, and the application scenarios are too single to meet the diverse needs of users. SUMMARY OF THE INVENTION [...
