Intelligent Digital Transformation Laboratory
The Intelligent Digital Transformation (IDT) Laboratory was established in 2020, as a successor to the e-Services, e-Learning & e-Government Lab that had been founded in 2008. It is part of the Information Technologies Institute of CERTH. The Lab focuses on research and development in the areas of video/image/multimedia understanding and artificial intelligence, and on how these technologies can be applied towards transforming various business sectors and the society at large. The Head of the IDT Laboratory is Dr. Vasileios Mezaris.
