Abstract
There is now growing interest in organizing and querying large bodies of
video data. In this paper, we will develop a simple SQL-like video query
language which can be used not only to identify videos in the library that
are of interest to the user, but which can also be used to extract, from
such a video in a video library, the relevant segments of the video that
satisfy the specified query condition. We investigate various types of
user requests and show how they are expressed using our query language. We
also develop polynomial-time algorithms to process such queries.
Furthermore, we show how video-presentations may be synthesized in
response to a user query. We show how a standard relational database
system can be extended in order to handle queries such as those expressed
in our language. Based on these principles, we have built a prototype
video retrieval system called VIQS. We will describe the design and
implementation of VIQS and show some sample interactions with VIQS.
