Abstract
This paper describes Vex: a programming system for extracting
content information from unstructured media. Vex poses the problem of
understanding media in terms of recognizing events in media streams.
Vex approaches this problem by adapting computer science tools for
matching patterns and parsing text. Vex allows the user to write an
application directly in terms of patterns and actions. Vex transforms
such a specification into a program that examines a stream of video,
recognizes when a specified pattern of imagery has appeared, and
performs the appropriate action.
Vex addresses important issues in both multimedia computing and
computer vision. As a multimedia tool, Vex is a language for
penetrating opaque media. In computer vision, Vex represents an
approach to building general purpose tools.
