Automatic Extraction of MPEG-7 Metadata for Audio Using the Media Asset Management System iFinder

Jobst Löffler, Joachim Köhler
Fraunhofer IMK, Sankt Augustin, Germany

This paper describes the MPEG-7 compliant media asset management system iFinder, which provides a set of automatic methods and software tools for media analysis, archiving, and retrieval. The core technology of iFinder comprises several modules for audio and video metadata extraction that are bundled in the iFinderSDK, a commercial product offered to the media industry. The workflow for audio content processing together with pattern recognition methods used will be presented. Of special note, a technique for precise audio- text alignment together with a browser application for synchronized display of retrieval results will be demonstrated. An insight to using MPEG-7 as a standardized metadata format for media asset management will be provided from a practical point of view.
