劇院照片是2011年開始發展的一種新的照片型態,照片中有著局部動態的效果,且該動態區域內影像的變化是連貫與不斷重複的。讓電腦來自動建置劇院照片是一個很大的挑戰,我們需要設計一個方法能夠在影片中選擇哪些區域該保留動態,而其它區域呈現靜態。現今建置劇院照片的工作,絕大多數皆是半自動的建置方法,在本論文我們提出一個全自動的方法建置劇院照片,著重的方向為如何去尋找影片中的有趣區域問題。首先,我們會輸入一段影片,接著結合多個影片特徵去計算影片內容的有趣度分數,並且找出的有趣區域有著最大的有趣值分數。這個問題可以被視為在圖形中找最大權重連接子圖的問題。我們的方法是很有效的,並且能夠結合多特徵與找出的區域為不規則的形狀。
