Ioannis Pitas, "Benchmarking of Still Image Watermarking Algorithms"

Monday, June 3, 2002, 12:30 - 1:30 PM EST

Bartos Theatre, MIT Media Lab (E15)

Electronic Publishing group

In recent years, we observed an explosion of R&D in watermarking towards intellectual property protection of digital media. Most of the research concentrated on still image watermarking. However, no proper benchmarking tools have been developed for assessing the performance of these techniques. Only ad hoc tools existed to this end. In this lecture, a new tool will be presented that is based on sound theoretical and experimental basis that can be used for benchmarking watermarking algorithms. This tool capitalizes on the experience gained at the AIIA Lab, University of Thessaloniki that has pioneered work in watermarking since the mid 90's. The effort has been supported by the EU R&D project CERTIMARK that specializes in digital media watermark benchmarking.

IOANNIS PITAS ( is a professor at the Department of Informatics, University of  Thessaloniki. He served as a Visiting Research Associate at the University of Toronto, Canada, University of Erlangen-Nuernberg, Germany, Tampere University of Technology, Finland and as Visiting Assistant Professor at the University of Toronto. His current interests are in the areas of digital signal/image processing, multidimensional signal processing and computer vision.  He has published over 370 papers, contributed to 14 books and authored, coauthored, edited, and coedited seven books in his areas of interest.

He is the coauthor of the books: "Nonlinear Digital Filters: Principles and Applications" (Kluwer, 1990); and "3D Image Processing Algorithms" (Wiley 2000).

He is the author of the books: "Digital Image Processing Algorithms" (Prentice Hall, 1993); "Digital Image Processing Algorithms and Applications" (Wiley 2000); and "Digital Image Processing" (in Greek, 1999).

He is the editor of the book: "Parallel Algorithms and Architectures for Digital Image Processing, Computer Vision and Neural Networks" (Wiley, 1993); and coeditor of the book "Nonlinear Model-Based Image/Video Processing and Analysis" (Wiley 2000).

Dr. Pitas has been a 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 is/was principal investigator in more than 25 competitive R&D projects, mostly funded by EU. He is/was Associate Editor of the IEEE Transactions on Circuits and Systems, IEEE Transactions on Neural Networks, IEEE Transactions on Image Processing, IEICE, Circuits Systems and Signal Processing (CSSP) and coeditor of Multidimensional Systems and Signal Processing. 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 was the general chair of IEEE ICIP2001.
