摘要

在此篇論文中，我們提出動作拼的方法來生成舞蹈動作，並讓舞步豐富，具體來說，我們使用虛擬的空間方向和速度為基底的同步方式展示空間對齊與時間對齊的技術，使用這些方法讓動作在拼接的時候看起來更加自然與流暢，因此，展示的拼接方法中，我們使用虛擬腳色的動作分層來重新生成動作可以讓動作的數量更多，此外，我們也實作DTW來混成兩個動作，使用DTW來生成一個下一個動作的建議列表，最後，生成的新動作證明這些方法是對於生成多樣的動作是有益的，且這些動作都是基於少量的非拼接的動作生成而來。

In this thesis, we present a motion splicing method for generating dance movements which make dance step more diversely. Specifically, we show that spatial and time alignment technique by using virtual direction and velocity-based synchronization for spliced movements looks natural and smooth. Hence, in the proposed motion splicing approach, it is possible to increase the number of generated motions as well as the number of desired actions that can be performed by virtual characters. Additionally, we implemented motion blending by using Dynamic Time Warping to produce a next motion table of recommendations. Finally, the generated results show that the proposed solution can be beneficially applied to generate varied movements as well as the dance movements which non-spliced with a small amount of motion database.
