Fraunhofer – Heinrich Hertz Institute (HHI)

 The Fraunhofer-Gesellschaft undertakes applied research of direct utility to private and public enterprise and of wide benefit to society. Its services are solicited by customers and contractual partners in industry and public administration. It maintains 56 research institutes, at over 40 different locations throughout Germany. The Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institute (HHI), in Berlin is a leading research institute in the fields of mobile broadband communications, photonic networks, electronic imaging and multimedia. Its Image Processing Department (HHI/IP) has a long experience in signal, image, and video processing. About 55 researchers in 25 research projects are working in fields related to multimedia and cover the whole chain including capture, analysis, coding, streaming, interaction and visualisation of 2D and 3D content. The applications range from mobile services to digital cinema, HDTV, 3DTV and immersive media. Research covers all fields from algorithm development to chip and systems design. HHI is renowned for its leading role in video coding standardisation within ISO/IEC MPEG, ITU-T VCEG, DVB and IETF. European and National research projects relevant to FascinatE are VISNET/VISNET2, 3DTV NoE, RUSHES, Games@Large (all FP6) and 3D4YOU, 2020-3D-MEDIA, MOBILE 3DTV, 3D PHONE, 3D Presence, SEA, OMP, MAGIC (all FP7). HHI is also leading two major German national research initiatives: PRIME, which deals with 3D production for film and broadcasting, and the Core Technology Cluster of THESEUS, researching semantic technologies for the Internet of Services. In FascinatE HHI will lead WP2 on audio-visual scene capturing, production networks and layered scene representation. In this context it will bring its expertise in designing capturing and coding systems for immersive media systems using panoramic video of highest spatio-temporal resolution into the project. This includes the design of a suitable multi-camera test-bed consisting of different types of cameras, the specification of a scalable format for generic and layered scene representation and for related coding schemes, the provision of an existing omni-directional multi-camera system (6kx2k) as background technology, its adaptation and integration into the capture test-bed, the implementation of a multi-camera test-bed with high-speed interfaces, networks and processing units, the development of algorithms needed for calibrating the whole system and for merging images from different cameras to one generic representation format and, finally, to integrate all in one entire real-time environment for project demonstrations. Apart from that, HHI will be responsible for system integration in WP1 and has minor contributions to WP3, WP5 and WP7.

Key People

Dr. Oliver Schreer

He graduated in Electronics and Electrical Engineering at the Technical University of Berlin in 1993. From 1993 until 1998, he was assistant teacher at the Institute of Measurement and Automation, Group of Control Theory and System Dynamics, responsible for lectures and practical courses in the field of image processing and pattern recognition. His research interests have been camera calibration, stereo image processing, 3D analysis, navigation and collision avoidance of autonomous mobile robots.

Since August 1998, he is working as project leader of the Immersive Media & 3D Video Group in the Image Processing Department of HHI. In this context he is engaged in research for 3D analysis, novel view synthesis, real-time video conferencing systems and immersive TV applications. From 2000 to 2003, he was the responsible person for the European IST-project VIRTUE at Heinrich-Hertz-Institute (HHI) and within this project he was leading the work package 2, “Real-time platform”. From February 2007 to July 2009, Dr. Oliver Schreer held the position of a project manager of the European FP6 project RUSHES on “Retrieval of multimedia Semantic units fro enhanced reusability” (www.rushes-project.eu). From January 2008 until July 2010, he was workpackage leader of the European FP7 project “3DPresence ” (www.3dpresence.eu). For Fascinate he is leading the workpackage on “Scene Capture, Production Networks & Layered Production”.

In November 1999, he finished his PhD in electrical engineering at the Technical University of Berlin entitled by “Stereo Image Processing and Navigation in Mobile Robotics”, Dissertation 1999, Mensch & Buch Verlag, Berlin, Germany, (ISBN 3-89820-060-4).

Since autumn 2001, Oliver Schreer is Adjunct Professor at the Faculty of Electrical Engineering and Computer Science, Technical University Berlin. He is giving a complementary set of lectures at the Communcation Systems Group of Prof. Thomas Sikora.

In the winter semester, the lecture is entitled “Stereo Image Processing in Videocommunications “, whereas, in the summer semester, the lecture is entitled “3D View Synthesis in Videocommunications”.

In June 2006, Oliver Schreer received his habilitation in the field of “Computer Vision / Videocommunication” at the faculty of Electrical Engeneering and Computer Science, Technical University Berlin. His habilitation thesis is a german lecture book on “Stereoanalysis and View Synthesis” published at Springer.

Since November 2006, Oliver Schreer is Assistant Professor (Privatdozent) at Institute of Computer Engineering and Microelectronics in the Computer Vision and Remote Sensing Group, lead by Prof. Olaf Hellwich.

He is guest editor for the IEEE Transactions on Circuits, Systems and Video Technology. Oliver Schreer is also editor of a book on “3D Videocommunication” published in 2005 at Wiley & Sons, UK.

Dr. Ralf Schäfer

Ralf Schäfer received his Dipl.-Ing. and Dr.-Ing. degrees both in electrical engineering from the Technical University of Berlin in 1977 and 1984 respectively. In October 1977 he joined the Heinrich-Hertz-Institut (HHI) in Berlin . From this time he worked in various fields of signal processing and image coding and he was leader of several research projects. Since 1989 he is head of the Image Processing Department. In the department he is responsible for about 50 researchers and technicians, about 40 students and about 30 R&D projects funded by the German Government (BMBF, BMWi), by the German Science Foundation (DFG), by the European Commission and by industries.

He participated in several European research activities like COST, EUREKA , RACE, ACTS, ESPRIT and IST and for a long period he was member of the Technical Module of the European DVB-project (TM-DVB), where he was chairing the Task Force on “Digital Terrestrial Television – System Aspects, which specified the DVB-T standard. He coordinated the German joint research projects HDTV-T, MINT and GigaMedia and INVINET.

Ralf Schäfer is member of the German “Society for Information Technology” (ITG), where he is chairman of experts committee “TV Technology and Electronic Media” (FA 3.1) and chairman of the experts group “Digital Coding” (FG 3.1.2). Furthermore he is member of the German “Society for Television and Motion Picture Technology” (FKTG), where he belongs to the URTEL Award Committee.

He serves permanently as independent expert and reviewer for the European Commission and he was Chairman or member of Programme Committees of many national and international conferences.
