dc.description.abstract | 在本篇論文中,我們提出一個從視訊資料庫中擷取某特定視訊資料的方 法 -- 利用視訊資料中物件的時間關係。我們將視訊資料或查詢資料轉為 一組有序的三重因子 (Oi,Oj,Rij) 所成的集合,其中 Oi以及 Oj 是指物 件,而 Rij 則代表 Oi 以及 Oj 間的時間關係。然後為視訊資料庫中視 訊資料的三重因子建構一個雜湊表,每一個三重因子會被分配到一個質數 。所以,每一個視訊資料可轉換成一個正整數 Pi 。查詢資料可藉由已建 構好的雜湊表得到相關的三重因子的值,而轉為一正整數 Pq。經由查詢 資料所得的結果即是 Pi/Pq 餘數等於零的視訊資料所成的集合。最後, 我們利用前述所提出的方法實作此一視訊資料庫查詢系統,而從系統執行 結果中,我們可以看到隨著資料庫記錄的增加,查詢的時間是呈現線性的 成長。 In this thesis, we propose a method of retrieving videos from thevideo database based upon the temporal relationship among the videos. We transform each video(query) into a set of ordered triples, (Oi,Oj,Rij)s, where Oi and Oj are two symbol objects and Rij is the temporal relationship between Oi and Oj. Then, we construct a hashing table for all the triples corresponding to the videos in the video database. Every ordered triple is assigned a prime number. So, each video Vi can be transformed into a positive integer value Pi. A query can be transformed into a positive integer value Pq via the preconstructed hashing table. The answer to a query is a collection of videos such that their corresponding Pi's can be divided by Pq, i.e., the remainder of Pi/Pq is equal to 0. A video database query system is built based upon the proposed method. From computation results, we notice that the query time increases linearly as the size of the video database grows. | zh_TW |
