Embodiment 1

[0076] Figure 1a It is a flow chart of a method for adding multi-user video special effects provided by Embodiment 1 of the present disclosure. This embodiment is applicable to the situation where video special effects are added for multiple different users in the video. This method can be added by multi-user video special effects The device may be implemented by means of software and / or hardware, and the device may be configured in a terminal device, such as a typical computer. Such as Figure 1a As shown, the method specifically includes the following steps:

[0077] S110. Identify at least one human body joint point of a target user matching the special effect adding interval in multiple image frames in the video that match the special effect adding interval, wherein the video includes multiple special effect adding intervals.

[0078] Generally speaking, video is formed by a series of static image frames played continuously at a very fast speed. In this way, the video ca...

Embodiment 2

[0112] figure 2 It is a flow chart of a method for adding multi-user video special effects provided by Embodiment 2 of the present disclosure. This embodiment is embodied on the basis of each optional solution in the foregoing embodiments. In this embodiment, identifying at least one human body joint point of the target user matching the special effect adding interval among multiple image frames matching the special effect adding interval in the video is embodied as: when it is determined that the special effect adding condition is satisfied , according to the current playback and / or recording progress of the video and the duration of the special effect addition interval, determine the start and end time points of the first special effect addition interval matching the special effect addition condition; according to the current playback and / or recording of the video progress, the duration of the special effect addition interval, the start and end time points of the first spe...

Embodiment 3

[0136] image 3 It is a flow chart of a method for adding multi-user video special effects provided by Embodiment 3 of the present disclosure. This embodiment is embodied on the basis of each optional solution in the foregoing embodiments. In this embodiment, according to the position information of at least one human body joint point of the target user in the plurality of image frames, the calculation of the motion characteristic parameters of the target user in the special effect adding interval is embodied as: In the special effect adding interval, according to the position information of at least one human body joint point of the target user in the plurality of image frames, calculate any The unit displacement between two adjacent image frames, and the motion displacement of at least one human body joint point of the target user in the special effect adding interval; counting the duration of the special effect adding interval, and and the movement displacement, determine...

Abstract

The invention discloses multi-user video special effect adding methods and device, terminal equipment and a memory medium. A method comprises the steps of in a plurality of image frames matching withspecial effect adding intervals within a video, identifying at least one human joint point of target users matching with the special effect adding intervals; computing motion feature parameters of thetarget users according to location information of the at least one human joint point of the target users; obtaining video special effects and special effect adding information if it is determined that the human joint points of the target users identified from target image frames satisfy a preset joint action condition, and adding the video special effects to video locations associated with the target image frames within the video; and computing motion scoring information of each user, and adding the motion scoring information to motion scoring settlement locations matching with the video. According to the embodiments of the invention, scene diversity of video interaction application can be improved.

Description

technical field [0001] Embodiments of the present disclosure relate to data technology, and in particular to a method, device, terminal device, and storage medium for adding multi-user video special effects. 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 The main channel of communication and entertainment. [0003] At present, video interactive applications can recognize the user's face, and add a static image on the user's head (such as 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 at the same time, the application scene is too single to meet the diverse needs of users. Contents of the invention [00...
