MPEG-7 enhanced ubi-multimedia access —Convergence of user experience and technology

Unlike early versions of MPEG, MPEG-7 is shifting from a data-compression standard to a multimedia content description standard. As a result, it will have much broader implications for the human-computer interaction research. There are countless ways that the MPEG-7 metadata description framework can enhance userspsila experiences in accessing multimedia content. In this paper, we will report the algorithms that we developed for automatic generation of MPEG-7psilas description schemes (DSs): a video Table of Contents DS to enhance active video browsing, a Summary DS to enable direct use of a meta-data producerpsilas annotation, and a Still Image DS to allow interactive content-based image retrieval. Experimental results and user studies demonstrated the usefulness of MPEG-7psilas meta-data framework and effectiveness of our proposed automatic DS generation techniques.
