Summary: | 碩士 === 國立交通大學 === 資訊管理研究所 === 83 === 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.
