摘要: 
近來隨著數位資訊的蓬勃發展以及網路的快速成長,多媒體的應用已越來越普及於日常生活中。例如像多媒體文件、數位圖書館、數位影音…等等。可預期的,依據視訊內容之特性,將龐大的多媒體資料進行適當之分類,可以達到有效的檢索與管理,這是多媒體應用領域中重要的研究方向。由於視訊可以視為許多鏡頭(shot)所組成,故欲達成上述目的之第一步,就是正確地偵測出視訊中所有的鏡頭。
本論文提出一個建立於模糊分類器與轉換期間改良之鏡頭轉換偵測機制。為了同時偵測突然式(abrupt)與溶解式(dissolve)兩種鏡頭轉換,並也考慮多種可能影響之因素,例如,快速物件移動,快速鏡頭移動,閃光等等,本論文分析出若干有效之特徵。此外,為了精確地偵測出溶解式鏡頭轉換區間,本論文提出一個轉換區間改良之法則。由於特徵之性質不同,本論文使用模糊理論整合八種不同之特徵,建構鏡頭轉換偵測之機制。由實驗結果分析,本論文提出之鏡頭轉換偵測機制,可以同時有效地偵測突然式與溶解式鏡頭轉換,並且可以精確地找出溶解式之轉換區域。

In this article, to identify the abrupt and dissolve shot transition, we proposed an algorithm of shot change detection based on fuzzy classifier and transition duration refinement. The key to the success of video content analysis is segmentation, which is to divide a complete video stream into several shots for further analysis. The identification of shots is possible with the help of the shot change detection, which is to locate the boundary of two consecutive shots. The proposed scheme can reduce the effect of fast object/camera motion and flashes for shot change detection. Furthermore, to accurately capture the duration of dissolve transition, the transition duration refinement algorithm was proposed. We extracted eight features as the input of fuzzy classifier to detect shot changes. The experimental results demonstrate our proposed scheme can not only detect abrupt and dissolve transitions well but also accurately locate their durations. Our proposed scheme can provide a better performance for abrupt and dissolve detection.
