摘要:

人体运动是信息交流的关键功能。在应用上,抖音等短视频风靡全球。用户希望添加更多的视觉特效,以追求创意和个性。在短视频平台上加入了很多特效。这些都给了用户更多的可能性来炫耀这些个性。传统的视觉特效制作方法是制作模板。然而,为了合成的完美,用户不得不繁琐地尝试去把握新模板的时机和节奏。本文旨在通过运动驱动代替传统的模板匹配来实现视觉特效的合成。我们提出了人工智能的方法来改善这种视觉特效合成。详细来说,是为了增加对人体的特殊效果。在这个系统中,骨架提取是至关重要的。我们还提出了一种新的LSTM形式,通过动作识别来找出用户的意图。实验结果表明,该系统能够更容易、更高效地生成短视频的视觉特效。

英文摘要:

Human motion is a key function to communicate information. In the application, short-form mobile video is so popular all over the world such as Tik Tok. The users would like to add more VFX so as to pursue creativity and personlity. Many special effects are added on the short video platform. These gives the users more possibility to show off these personality. The common and traditional way is to create the template of VFX. However, in order to synthesis the perfect, the users have to tedious attempt to grasp the timing and rhythm of new templates. It is not easy-to-use especially for the mobile app. This paper aims to change the VFX synthesis by motion driven instead of the traditional template matching. We propose the AI method to improve this VFX synthesis. In detail, in order to add the special effect on the human body. The skeleton extraction is essential in this system. We also propose a novel form of LSTM to find out the user's intention by action recognition. The experiment shows that our system enables to generate VFX for short video more easier and efficient.
