The ultimate goal of visualization technologies is to visualize on a display (device) a ‘perfect’ representation of a 3D scene. This goal will be achieved when a scene visualized on a display is indistinguishable from the real one. Although, today’s display technology is still not able to reproduce such level of realism (visual quality), the requirements for achieving this are quite well understood. In this talk we will discuss the concept of light field as the underlying principle for a complete description of a 3D scene. We will show its formal definition through the plenoptic function and introduce several light field representations with the corresponding interpretation in spatial and frequency domain. Scene representations ranging from pure image-based, such as Epipolar-Plane Image (EPI) based, to multi-view multi-depth based will be considered. We will also look into available light-field displays that are trying to generate the required light field defined by a scene. We will end the talk by pointing out advantages and disadvantages of those displays over more widely available off-shelf 3D displays (e.g. autostereoscopic and glasses-based 3D displays).



Robert Bregović received the Dipl.Ing. and M.Sc. degrees in electrical engineering from the Faculty of Electrical Engineering and Computing, University of Zagreb, Zagreb, Croatia, in 1994 and 1998, respectively, and the Dr. Tech. degree in information technology from the Tampere University of Technology, Tampere, Finland, in 2003. From 1994 to 1998, he was an Assistant at the Department of Electronic Systems and Information Processing, Faculty of Electrical Engineering and Computing, University of Zagreb. Since 1999 he is with the Department of Signal Processing, Tampere University of Technology, where he is currently working as a Senior Researcher. In 2005 and 2006 he was a visiting Research Fellow at Nanyang Technological University, Singapore, and in 2013 he was a Senior Researcher at HolografikaKft. Budapest. His research interests are in the design of filters and filter banks, multi-dimensional signal analysis and light field sensing, processing and display.
