Querying Video Libraries

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.

Algebraic Multimedia: Theory and Implementation

Storage, processing, and presentation of multimedia data, such as images, video, audio, or multimedia presentations, has become an important area of computer science. The goal of this dissertation is to formalize access methods to multimedia data by developing algebras that operate on PowerPoint presentations, video, and audio as in the case of relational algebra operating on tabular data. This dissertation also proposes ways to create summaries of multimedia data
