dc.description.abstract本论文设计并实作效率良好之视讯资料库系统。主要可分为视讯资料的切割,找出视讯资料中的场景。以及建立视讯资料场景的索引,最后提供使用者检索查询。
在视讯资料的前端处理部分可再区分为场景变化侦测方面与视讯资料的索引。利用Fuzzy C-Means模糊分群演算法来判断是否发生场景变化。在判断出场景变化的发生点后,可以藉此将影像切割成一段一段的场景,再由各段场景内取出具代表性的关键视讯框,提供建立检索的依据。
检索建立的部分,依照前一步骤取出的关键视讯框,利用物件的时间关系来定义各个关键视讯框所代表的数对,以这些数对为基础来建立索引值。并利用这些索引值计算出各段影片的特征值。在使用者查询时利用模数计算的方法来判断场景是否存在于影片之中。
本论文所实作的查询系统,运用的演算法有相当良好的效率。经由实验结果发现,确实有良好的效率。

dc.description.abstractThe system described in this theisis can provide query service for user. This video query system is quite efficient. Primary tasks in the query system are scene change detection on video data to get the position of shots and video indexing and querying. We could provide querying and retrieving videos for users' need.
On scene change detection, Fuzzy C-Means algorithm is using for calculating feature data in video data and detecting scenes change. After we know the scene-change position, we could cut video into shots and get key frames from shot for indexing and querying.
On indexing and querying, we use object temporal relationship to define triples represented to every key frame. These triples are used to build indexing. Standing values of every video can be got from those indexing value. At the time of user querying, we could use modular expression to know if the shot is existed in video.
