Dimitrios Tzovaras

Dimitrios Tzovaras received the Diploma degree in electrical engineering and the Ph.D. degree in 2D and 3D image compression from Aristotle University of Thessaloniki, Thessaloniki, Greece, in 1992 and 1997, respectively. He is a Senior Researcher in the Informatics and Telematics Institute of Thessaloniki. Prior to his current position, he was a Senior Researcher on 3D imaging at the Aristotle University of Thessaloniki. His main research interests include virtual reality, assistive technologies, 3D data processing, medical image communication, 3D motion estimation, and stereo and multiview image sequence coding. His involvement with those research areas has led to the coauthoring of more than 35 papers in refereed journals and more than 80 papers in international conferences. He has served as a regular Reviewer for a number of international journals and conferences. Since 1992, he has been involved in more than 40 projects in Greece, funded by the EC, and the Greek Secretariat of Research and Technology. He is an Associate Editor of the EURASIP Journal on Advances in Signal Processing and a Member of the Technical Chamber of Greece.
