"3D Holoscopic Content Coding: Recent Advances"

Title: 3D Holoscopic Content Coding: Recent Advances
Date: June 9th 2015
Time: 16:15
Place: L111, Campus Sundsvall, Mid Sweden University

Holoscopic imaging, also known as integral, light field, and plenoptic imaging, derives from the fundamentals of light field sampling, where not only spatial information about the three-dimensional (3D) scene can be captured but also angular information, i.e., the “whole observable” (holoscopic) scene. It is an appealing technology for glassless 3D video systems, which has recently emerged as a prospective candidate for future image and video applications. However, the success of this technology with respect to mass market adoption requires that some obstacles are overcome. Notably, adequate coding tools that can efficiently handle 3D holoscopic image and video are necessary. Additionally, display scalable approaches are important in order that legacy devices may handle this type of content adequately. This presentation will highlight some of the key aspects of the 3D holoscopic image video coding, and will describe some state-of-the-art approaches that have been develop in the last years in this field of research.

Paulo Nunes is currently with the Multimedia Signal Processing Group (MSP-lx) of the Instituto de Telecomunicações, where he has been a Researcher since 1995. In addition, since 2000, he is also with the University Institute of Lisbon (ISCTE-IUL), Portugal, where he is currently an Assistant Professor at the Information Science and Technology Department, teaching multimedia communications, computer networks and signal processing. His research interests include 3D video, object-based and frame-based video coding, as well as video bit-rate control. He has contributed more than 50 papers to international journals and conferences in these areas. In addition, he has participated in the work of ISO/MPEG during the development of the MPEG-4 Visual standard. He has also participated in the RACE MAVT and ACTS MoMuSys projects, and the IST networks of excellence VISNET and VISNET-II, where he was responsible for the development and implementation of non-normative video coding tools in the field of bit-rate control, and the FP7 3D-VIVANT project, dealing with 3D holoscopic video technology, as the leader of the work package on 3D holoscopic content processing and coding. Currently, he is a member of the Management Committee of the COST Action IC1105 on “3D Content Creation, Coding and Transmission over Future Media Networks”. In parallel, he has acted as a reviewer for several IEEE, ACM, SPIE and EURASIP journals and conferences. In 2007, he was a member of the organizing committee of the Picture Coding Symposium (PCS). In 2014 he was the Publicity Co-Chair of the European Signal Processing Conference (EUSIPCO) and the International Conference on Telecommunications (ICT). In 2015 is the Technical Program Co-Chair of the 3DTV-CON. He is currently, a vice-chair of the Image, Video & Mesh Coding Interest Group of Multimedia Communications Technical Committee of the IEEE Communications Society.
