| dc.description.abstract | 動作擷取系統常用來製作極其自然的動畫，但無法將動作擷取系統的裝備用在動物上。另一種擷取動作的方式是使用一段影片，自動地從影片中角色的動作擷取出來。因為全自動的擷取方式會使結果不盡理想，所以我們在擷取動作的流程中透過使用者的幫助來讓結果更好。
這篇論文提出一個半自動的方式從一段影片中擷取出動畫資訊。首先從影片分離出角色的資訊並對影片做分析，接著使用者提供一個帶有骨架資訊的參考三維模型。使用者調整參考模型使之與開始影格中的角色輪廓相符，並指定角色與參考模型所對應的身體與四肢的輪廓。接著系統會自動地在每一個往後的影格中估計參考模型的姿勢來重建角色動作，之後，使用者透過介面修正估計結果。此論文的結果將會比電腦視覺領域中全自動的擷取方式要來得好。 我們的系統提供使用者一個易用且有效率的介面來擷取動物動畫，即使是未受訓練的使用者也可輕易達成。 | zh_TW |
