Stefanos Zafeiriou was born in Thessaloniki, Greece in 1981. He received the B.Sc, degree in Informatics with highest honors in 2003 and the Ph.D degree in Informatics in 2007, both from the Aristotle University of Thessaloniki, Thessaloniki, Greece. He has co-authored over 15 journal and 17 conference publications. During 2007-2008 he was a senior researcher at the Department of Informatics at the Aristotle University of Thessaloniki. Currently, he is a senior researcher at the Department of Electrical and Electronic Engineering at Imperial College London, UK. His current research interests lie in the areas of signal and image/video processing, computational intelligence, pattern recognition, machine learning, computer vision and detection and estimation theory. Dr. Zafeiriou received various scholarships and awards during his undergraduate, Ph.D. and postdoctoral studies. He was a finalist of the European Biometric Research Award in 2006 and he was nominated for the prestigious Cor Baayen Award 2008.
In this lecture will present research work that includes watermarking and copy detection of multimedia objects, biometrics and affect recognition, design and theoretical investigation of classifiers and clustering techniques, design and theoretical investigation of component analysis techniques for signal processing and representation with a special interest to nonnegative component analysis and stochastic prediction of dynamic system state with application to object and camera tracking. Moreover, I will discuss on some of my current research interests which involve object recognition/reconstruction using photometric stereo, design of Brain Computer Interfaces (BCI), analysis of biomedical signals and emerging biometric techniques.
