The computer vision and digital image processing team at the University of Thessaloniki is an active research group working for more than one decade in digital image processing and related areas. It consists of two faculty members, one postdoctoral fellow and ten PhD students. Its topics of interest span the areas of digital audio/image/video processing and analysis, computer vision, data fusion, access control systems, watermarking and IPR. It has undertaken 21 R\&D projects (mostly European ESPRIT, ACTS, HCM). Among those the following projects are relevant to the current project:

  • NOBLESSE, Nonlinear Model-Based Analysis and Description of Images for Multimedia Applications, ESPRIT, EU.
  • M2VTS, Multimodal Person Verification, ACTS, EU.
  • Development of Digital Signatures for Multimedia Applications, Greek Ministry of Technology.
  • MAVI, Model Based Analysis of Video Information, Human Capital and Mobility, EU.
  • Image Sequence Processing and Analysis, Greek Ministry of Technology.

As a result of this research more than 280 publications have appeared in international scientific journals, books, book chapters and conference proceedings. The book "Nonlinear Digital Filters: Principles and Applications" authored by I. Pitas and A.N. Venetsanopoulos published by Kluwer Academic in 1990 is another result of the research performed. The book "Digital Image Processing Algorithms" authored by I. Pitas was published by Prentice Hall in 1993. The book "Parallel Digital Image Processing Algorithms" edited by I. Pitas was published in 1993 by J. Wiley. The group has strong cooperation with other Universities, research centers and industrial partners in the area of its interests through projects mainly funded by the European Union.

Ioannis Pitas received the Diploma of Electrical Engineering in 1980 and the PhD degree in Electrical Engineering in 1985 both from the University of Thessaloniki, Greece. Since 1994, he has been a Professor at the Department of Informatics, University of Thessaloniki. Dr. Pitas has been member of the European Community ESPRIT Parallel Action Committee. He has also been an invited speaker and/or member of the program committee of several scientific conferences and workshops. He was Associate Editor of the IEEE Transactions on Circuits and Systems and co-editor of Multidimensional Systems and Signal Processing and he is currently an Associate Editor of the IEEE Transactions on Neural Networks. He was chair of the 1995 IEEE Workshop on Nonlinear Signal and Image Processing (NSIP95). He was technical chair of the 1998 European Signal Processing Conference. He is the chair of the upcoming 2001 IEEE International Conference on Image Processing.

Constantine Kotropoulos received the Diploma degree with honors in Electrical Engineering in 1988 and the Ph.D. degree in Electrical & Computer Engineering in 1993, both from the Aristotle University of Thessaloniki. From October 1997 to January 2002 he served as a Lecturer at the Department of Informatics. He currently is an Assistant Professor at the same department. Dr. Kotropoulos participated into 14 research projects financed by national or European funds. He authored 17 journal papers and 68 conference papers and contributed 5 chapters to edited books in his areas of expertise. More than 100 citations have been made by the scientific community to his published works. He is the co-editor of the book "Nonlinear Model-Based Image/Video Processing and Analysis" published by J. Wiley and Sons, 2001. His current research interests include multimedia signal processing, multimedia information retrieval, pattern recognition, statistical language engineering, virtual reality, and computer graphics.

Marios Gavrielides received his Bachelors and Master of Science degrees in Electrical Engineering at the University of South Florida in Tampa, Florida and his Ph.D. degree in Biomedical Engineering at Duke University, Durham, North Carolina in 2001. His dissertation topic was "A computer aid for the automatic detection of microcalcification clusters in digitized mamograms" and his advisor was Dr. Carey E. Floyd, Jr. Dr. Gavrielides was a recipient of a dissertation award from the Susan G. Komen Breast Cancer Foundation. He is currently a post-doctoral researcher at the Department of Informatics at the Aristotle University of Thessaloniki. His research interests include Medical Imaging and Perceptual Feature extraction towards image and video content-based retrieval (here is his resume).

Zuzana Cernekova received the Diploma of Master of Science in 1999 at Comenius University Bratislava, Slovakia. She was a researcher and lecture assistant and she was studying toward a Ph.D. at the Department of Computer Graphics and Image Processing, Faculty of Mathematics and Physics, Comenius University. She is currently a pre-doc researcher at the Department of Informatics, University of Thessaloniki. Her research interests lie in the areas of video processing and pattern recognition. Ms. Cernekova is a member of the SCCG organizing committee.

Pawel Rotter has received the Diploma of Master of Science in Automatic Control at the University of Mining and Metallurgy (UMM), Krakow, Poland in 1999. Since 1999 he has been studying toward Ph.D. at the Institute of Automatic Control at the UMM. His research interests are related to still image analysis, especially image retrieval using model objects. He is currently a pre-doc researcher at the Department of Informatics, Aristotle University of Thessaloniki, Greece.

Elena Sikudova received the Master of Science degree in the field of computer graphics at Comenius University Bratislava, Slovakia. She was a lecture assistant and Ph.D. student at the Department of Computer Graphics and Image Processing, Faculty of Mathematics and Physics, Comenius University. She has a Master of Arts degree in the field of economics from the Pittsburgh University, PA, USA. Currently she is a pre-doc researcher at the Department of Informatics, University of Thessaloniki, Greece. Her research interests lie in the area of genetic algorithms. Ms. Sikudova is a member of the SCCG organizing committee.
