Box 361, Greece Received 29 April 2002 and in revised form 22 November 2002 An Authoring tool for the MPEG-4 multimedia standard integrated with image sequence analysis algorithms is described. MPEG-4 offers numerous capabilities and is expected to be the future standard for multimedia applications. However, the implementation of these capabilities requires a complex authoring process, employing many different competencies from image sequence analysis and encoding of audio/visual/BIFS to the implementation of different delivery scenarios: local access on CD/DVD-ROM, Internet, or broadcast. However powerful the technologies underlying multimedia computing are, the success of these systems depends on their ease of authoring. In this paper, a novel Authoring tool fully exploiting the object-based coding and 3D synthetic functionalities of the MPEG-4 standard is described. It is based upon an open and modular architecture able to progress with MPEG-4 versions and it is easily adaptable to newly emerging better and higher-level authoring and image sequence analysis features. Keywords and phrases: MPEG-4, Authoring tools, image sequence analysis.

EURASIP Journal on Applied Signal Processing INTRODUCTION
MPEG-4 is the next generation compression standard following MPEG-1 and MPEG-2. Whereas the former two MPEG standards dealt with coding of general audio and video streams, MPEG-4 specifies a standard mechanism for coding of audio-visual objects. MPEG-4 builds on the proven success of three fields [1, 2, 3]: digital television, interactive graphics applications (synthetic content), and interactive multimedia (worldwide web, distrib
