"Signal Processing Based Research Issues in 3DTV"

A typical 3DTV chain has capture, representation, compression, transmission, display interface and display stages. Each stage has its own specific nature and problems. And there are many alternative technologies for implementing each of these functional units. Signal processing tools play an important role in each such stage. The capture unit deals with difficult video data fusing problems. The post capture signal processing needs may range from nil in simplest 3DTV operations to demanding time-varying 3D model generation in sophisticated ones. Coding and compression of 3DTV video has its own specific nature and solutions. Probably the most complicated and demanding signal processing is at the display interface stage since 3D displays are quite different than 2D displays, and furthermore, since 3D displays come in many different forms. There are signal processing needs even within the camera and displays units. Among all different 3D modes, true 3D versions whichtarget physical duplication of information carrying light, such asholography and integral imaging, have their own rich signal processing needs. The signal processing problems associated especially with holographic 3DTV are unique and by far more demanding, and therefore, has the potential to trigger a new line of sophisticated signal processing techniques and associated mathematics.

"Telepresence : from Virtual to Reality"

The teleconferencing industry newsletter Wainhouse Report defines Telepresence as "a videoconferencing experience that creates the illusion that the remote participants are in the same room with you." Today Telepresence is embodied in the marketplace by solutions such as HP Halo and Cisco Telepresence, dedicated conference rooms sporting built-in furniture and life-sized high-definition video, costing hundreds of thousands of dollars per room. In the future, Telepresence systems will be more diverse, enabling connections between not only meeting rooms but also offices, hotel rooms, vehicles, and even large unstructured spaces such as conference halls and stadiums. Mixed reality as well as ubiquitous computing - including robotics - will play key roles, because these systems will not only need to immerse the participants in a common world, but will also need to empower the participants in ways that are better than being physically present. In this talk, I will take you on a tour of various component technologies as well as experiences that are being developed in Microsoft Research for the future of Telepresence. Along the way will be evident many opportunities for advances in multimedia signal processing.

"Protected Video Distribution in the Networked Age"

The way in which professional music is distributed and consumed has changed dramatically over the last 10 years. For this transitional period, the three key concepts that stand-out are ‘Napster’, ‘iPod’ and Digital Rights Management (DRM). Currently, we have arrived at a stable situation where most of the digital audio distribution is controlled by a single retailer, and digital music is no longer encumbered by DRM. However, it is unclear that the distribution and consumption of professional digital video will follow the path of digital music. It might very well be that the future of digital video will include a strong DRM component. Why this might be the case, what form distribution of digital video will take, and why the inclusion of DRM might be less controversial than feared, will be the topic of this talk.

Ton Kalker is a Distinguished Technologist at Hewlett-Packard Laboratories. He made significant contributions to the field of media security, in particular digital watermarking, robust media identification and interoperability of Digital Rights Managements systems. His history in this field of research started in 1996, submitting and participating in the standardization of video watermarking for DVD copy protection. His solution was accepted as the core technology for the proposed DVD copy protection standard and earned him the title of Fellow of the IEEE. His subsequent research focused on robust media identification, where he laid the foundation of the Content Identification business unit of Philips Electronics, successful in commercializing watermarking and other identification technologies. In his Philips period he has co-authored 30 patents and 39 patent applications. His interests are in the field of signal and audio-visual processing, media security, biometrics, information theory and cryptography.Joining Hewlett-Packard in 2004, he focused his research on the problem of non-interoperability of DRM systems. He became one of the three lead architects of the Coral consortium, publishing a standard framework for DRM interoperability in the summer of 2007. Subsequently he served as chair of the Technical Working Group of DECE. He participates actively in the academic community, through students, publications, keynotes, lectures, membership in program committees and serving as conference chair. He is one of the co-founders of the IEEE Transactions on Information Forensics. He is the former chair of the associated Technical Committee of Information Forensics and Security. He served for 6 years as visiting faculty at the University of Eindhoven. He is currently a visiting professor at the Harbin Institute of technology.

"On the sampling and compression of the plenoptic function"

Image based rendering (IBR) is a promising way to produce arbitrary views of a scene using images instead of object models. In IBR, new views are rendered by interpolating available nearby images. The plenoptic function, which describes the light intensity passing through every viewpoint in every directions and at all times, is a powerful tool to study the IBR problem. In fact, image based rendering can be seen as the problem of sampling and interpolating the plenoptic function.We therefore first briefly review some classical results on the spectral properties of the plenoptic function and then provide a closed-form expression for its bandwidth under the finite-field-of-view contraint. This naturally leads to an adaptive sampling strategy where the local geometrical complexity of the scene is used to adapt the sampling density of the plenoptic function. In this context, we also present an adaptive images-based-rendering algorithm based around an adaptive extraction of depth layers, where the rendering system automatically adapts the minimum number of depth layers according to the scene observed and to the spacing of the sample cameras. Finally, we discuss the problem of compressing the multiple images acquired for image-based rendering and present competitive centralized and distributed compression algorithms.This talk is based on work done with a number of collaborators, in particular, M. Brookes (ICL), C. Gilliam (ICL), A. Gelman (ICL), V. Velisavlievic (Deutsche Telekom) and J. Berent (Google inc.).

Pier Luigi Dragotti is currently a Senior Lecturer (Associate Professor) in the Electrical and Electronic Engineering Department at Imperial College, London.

"High Definition Communication - What it takes to implement it and what difference does it make?"

The audio quality of voice connections has remained virtually unchanged for more than 100 years. In most cases the audio bandwidth is still constrained to 3.5 kHz and nobody should expect to recognize, by listening to the sound, what is going on in the background of a call. With IP connections being used more and more for voice communication several attempts are now made to improve the situation. Some propose to considerably increase the audio bandwidth while others go as far as to promote communication in "CD-Quality" which could even include stereo or multi channel audio to fully transmit the accoustical image of the background of the speaker. What are the benefits to the user and what does it take to implement such services, as far as the audio components are concerned? This talk will try to give an overview about various systems proposed and what difference they can provide in user experience.

Bernhard Grill was born in Schwabach, Germany, in 1961. He received a M.S. (Diplom) degree in electrical engineering from the University of Erlangen-Nuremberg. During his days at the Fraunhofer Institute for Integrated Circuits IIS (1988-1995) and the University of Erlangen-Nuremberg (1995-1998) he contributed to the development of several per-ceptual audio coder systems. These include OCF, ASPEC, ISO/IEC MPEG-1/2 Audio Layer-3 (mp3), and MPEG-2 Advanced Audio Coding (AAC). Later work concentrated on sca-lable audio coding, now part of MPEG-4 Audio. In 1999 Bernhard Grill was back to Fraunhofer IIS, and two years later attained his Ph.D. in electrical engineering. He is currently the head of the Audio Department. His latest works include MP3 Surround and MPEG-Surround, the latter standardised in 2006. Further projects are Digital Rights Ma-nagement, multimedia transport over IP and broadcast applications. In September 2000 he received the Fellowship Award of the Audio Engineering Society for his work on MPEG-4 Audio and scalable audio coding. In October 2000, he and two colleagues were presented with the "German Future Award" of the German President for their work on MP3.

"Interactive Digital Art, a need for authoring tools to orchestrate the multimodal interaction between spectators
and Art pieces"

Interactive poly-artistic works is a type of expression becoming increasingly common nowadays. Consequently, users, specta(c)tors, expect more and more to play an active part in these works. Such creations always require the use of a wide range of techno-logies (3D video and audio display, video and audio synthesis, body tracking…), and a large number of computer environments, software and frameworks have been created to fulfill these needs. However, despite this important profusion in terms of technical tools, several issues remain unsolved when realizing such artistic works. First, in the context of collaborative arts, existing frameworks do not provide means for con-ceptualizing art pie-ces for contributors coming from different artistic areas (composition, choreography, video, 3D graphics…). Second, establishing communications between software or hardware components is often complicated. Finally, the communication process and its language have to be redefined from scratch for each new realization. We will introduce ConceptMove which is a unified paradigm for describing interactive poly-artistic works.
In the second part of this talk we will focus on Interactive Storytelling, which can be regarded as a new genre, deriving both from interactive media such as video games and from narrative media such as cinema or litterature. Whatever degree of interactivity, free-dom, and non-linearity might be provided, the role that the interactor is assigned to play always has to remain inside the boundaries thus defined by the author, and which convey the essence of the work itself. This brings an extra level of complexity for writers, when tools at their disposal remain limited compared to technological evolutions.

Stéphane Donikian received his M.S. (1989), PhD (1992) and Habilitation to direct research (2004) from the University of Rennes 1. From 1994 to March 2007, he has been Research Scientist for CNRS and is now Research Director at INRIA. He has been member of the SIAMES project at IRISA between 1989 and 2006. In September 2006 he founded the Bunraku team whose main scientific objective is to allow real and virtual humans to naturally interact in a shared virtual environment. His research interests include Virtual Reality, Virtual Humans, Reactive and Cognitive Behavioural Animation, Informed Virtual Environments, Scenario Authoring Tools for VR applications, Interactive Drama, and VR Middleware. He has conducted or participated to several national and European research projects with industrial and academic partners. He is the initiator and co-founder in Ja-nuary 2009 of Golaem, a company spinned off by Bunraku. Since November 2009, he is in vacancy of INRIA to work as CTO of Golaem.
