This book collects the research work presented at the Third International Conference on Audio- and Video- Based Biometric Person Authentication that took place in Halmstad, Sweden, in June 2001.
As in the preceding two cases, the conference announcement met with a consistent positive response both from industry and the research community. Since 1997, when the rst conference took place, the eld of Biometric Person Authentication has witnessed the development of commercial solutions that testify the practical relevance of the sub ject. On the other hand, the high quality of the research papers collected in this volume conrms the scientic importance and the challenging nature of the problems underlying this multi-disciplinary research eld.
