(EN) Multi-user video special effect adding methods and device, terminal equipment and memory medium
(ZH) 多用户视频特效添加方法、装置、终端设备及存储介质
Abstract
(EN)
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.
