TECHNICAL PROGRAM OVERVIEW

Welcome to TENCON’97 and Brisbane. This Conference comes at a time of a tremendous public awareness and concern about how technology is impacting our present and future. Our future social and economic well being will greatly depend on the successful application of technology to: development of new products, improvement of existing products, and provision of affordable high quality services. In trying to keep up with the ultra-fast growing area of electronics, computers and communications, the Organising Committee for this 12th IEEE Region 10 Conference chose the theme: ‘Speech and Image Technologies for Computing and Telecommunications’.

The response to the TENCON call-for-papers has been overwhelming. After the review, the Technical Program Committee accepted more than 200 papers for regular presentations. Unfortunately, many fine proposals could not be accommodated. For those authors whose abstracts were declined, we express our regret and thank them for their interest.

More than 50% of the submissions came from overseas and mainly from the Asia Pacific region. Overall, the submissions came from more than 20 countries including Asia and Europe.

To provide attendants with better access to paper presentations, we have a balanced number of oral and poster presentations. 55% of the papers were allocated to poster sessions, distributed in nine sessions. The oral presentations are distributed in 15 sessions. The decision on whether a paper be an oral or a poster presentation is not based on the quality of the paper but rather on the subject matter. For the oral papers, 15 minutes are allocated to each. For the posters, during the first 10 minutes, the authors will provide a minute brief introduction to their posters.

The technical program is highlighted by three Plenary Lectures, two Tutorials, and nine Invited Special Sessions. The topics for the three Plenaries are: ‘Applications of Three-Dimensional Signal Processing for Object-tracking and Image Compression’ by Prof. Bruton from The University of Calgary, Canada, ‘Signal Processing Challenges in Telemedicine’ by Prof. Smith from the Georgia Institute of Technology, USA, and ‘Speech and Audio Processing for Multimedia Communications’ by Prof. Lee from Lucent Technologies, New Jersey, USA.

T h e two highly acclaimed Tutorials cover the areas of speech a n d image technologies and will b e given by Prof. Rao from the University of Texas, USA (‘Multimedia Audiovisual Communication Services’) and Prof. Lee (‘Fundamentals of S p e a k e r a n d Utterance Verification with Applications’).

A new feature that w e included in this Conference is t h e series of nine invited special lectures dealing with current t rends in technology topics such as Video-on- Demand, Intelligent Agents, Speech a n d Video Compression which will be covered by experts in t he field (see timetable for details).

We a r e indebted to the Plenary Speakers , Tutorials Presenters , Special Sess ions S p e a k e r s and all the contributing authors for their efforts a n d contributions to make t h e Conference a success. Special thanks should g o to the staff within t h e School of Electrical and Electronics Sys tems Engineering, Queensland University of Technology for their continuous support and help in preparing t h e Conference booklet a n d the Proceedings.

Last but not least, we thank the members of the Organising Committee for all their efforts a n d the members of the Technical Program Committee for devoting time and effort to careful reviewing of t h e submitted papers.

A MESSAGE FROM THE GENERAL CHAIR

On behalf of the steering and technical committees, I would like to welcome you to TENCON'97. The theme of the Conference is 'Speech and Image Technologies for Computing and Telecommunications', a theme which is occupying the minds of the commercial and academic worlds as we see the convergence of multimedia and virtual reality with the mobility of communications and the power of computing.

TENCON is the Annual Region 10 Conference of the Institute of Electrical and Electronic Engineers (IEEE). Region 10 covers the Asia Pacific region. TENCON is held each year in one of the Region 10 countries and is traditionally a conference which combines both depth and breadth of treatment of the chosen theme. The Conference this year consists of plenary sessions, invited speakers who will present topics in depth, presented papers by academics and industry researchers and poster papers which will give opportunities to speak with authors about their work. In addition, two workshops covering speech and image processing respectively will precede the Conference and a related Conference entitled Workshop on Signal Processing Applications (WoSPA) will follow the Conference.

The Conference will be held at the Queensland University of Technology. The campus of the university is in the middle of the Central Business District of Brisbane, in easy reach of hotels and directly across the river from the South Bank Parklands, previously the site of EXP0'88. The campus is also adjacent to the City Botanical Gardens and Parliament House, providing an opportunity to enjoy some restful hours strolling along the river bank.

On Monday, 1 December 1997, two Tutorials will be held. These are respectively, 'Multimedia Audiovisual Communication Services', given by Professor K R Rao of the University of Texas at Arlington, USA and 'Fundamentals of Speaker and Utterance Verification with Applications', by Professor Chin-Hui Lee, Head of the Dialogue Systems Research Department, Bell Labs, Lucent Technologies, USA. After these workshops, a Civic Reception will be given by the Lord Mayor of Brisbane, Councillor Jim Soorley, in the function room of City Hall. Delegates and their partners will receive a special invitation from the Lord Mayor.

On Tuesday afternoon, a bus trip to Surfers Paradise on the Gold Coast has been arranged. A period of sightseeing will be followed by dinner and entertainment at the Nara Sea World Resort, attended by the Mayor of the Gold Coast, Councillor Gary Baildon. This function has been heavily subsidised by the Queensland Government and the Gold Coast Mayor. It is hoped that many delegates will take this opportunity to discover the beauty of the region in what is perhaps a once in a lifetime chance to do so.

V


On t h e Wednesday evening, t he formal Conference dinner will be held in the function rooms of Parliament House adjacent to the QUT. This will be hosted by a Minister of Parliament, t h e Honourable S a n t o Santoro M I A , Minister for Training and Industrial Relations.

Each d a y will commence with a Keynote address by a n eminent researcher. Professor Len Bruton of the University of Calgary will s p e a k on 'Applications of Three-Dimensional Signal Processing for Object-Tracking and Image Compression', Dr. Mark Smith from Georgia Tech will s p e a k on 'Signal Processing Challenges in Telemedicine' and Professor Chin-Hui L e e will s p e a k on 'Speech a n d Audio Processing for Multimedia Communications'. These speakers will present graphic illustrations of t h e challenges facing researches in developing speech a n d image technologies for t h e future.

I would like to encourage you to see this even t as a n opportunity to meet with other IEEE members from our region and to benefit from e a c h other's experiences and knowledge in this sunny part of the world. T h e organisers will have m a d e every effort to ensu re that your a t tendance will b e a pleasant a n d memorable event.

TENCON’S7 KEYNOTE ADDRESS ON ENGINEERING EDUCATION

SIGNAL PROCESSING AND COMMUNICATIONS: STRATEGIES FOR SUCCESS IN THE 2IST CENTURY

Professor Boualem Boashash Director, Signal Processing Research Centre

Queensland University of Tech nology Australia

Abstract

Signal Processing is arguably the fastest growing technology in electronics and communications engineering and has widespread other applications. In fact, it would be difficult to find today an application that does not make use directly or indirectly of signal processing concepts and technologies. QUT established in 1991 a university research centre in this field, the Signal Processing Research Centre (SPRC). In 1997, the SPRC has become a world leader in the field as measured by the quality of its publications and graduates. The principles put in place to achieve this success are described and shown to be a must for any academic unit that values excellence in teaching, research or scholarship. The signal processing undergraduate stream is then described, and an overview of selected research projects and key areas of applications are given as an illustration of these principles.
