JPEG Pleno Holography Workshop Announcement (Geneva)
JPEG calls for industry/academic participation to its workshop on JPEG Pleno Holography. This free public workshop will be held in Geneva on Tuesday the 19th of March 2019 in conjunction with the 83rd ISO/IEC JTC1/SC29/WG1 (JPEG) Meeting.
JPEG Pleno intends to provide a standard representation framework to facilitate the capture, representation, and exchange of light field, point cloud and holographic imaging modalities. This goal requires the specification of system tools, coding tools, and appropriate metadata, not only for efficient compression but also for data and metadata manipulation, editing, random access and interaction, protection of privacy and ownership rights, as well as security management. The standardization of the JPEG Pleno framework architecture, including a file format, and a light field coding solution is currently ongoing, and the JPEG committee plans to initiate the Call for Proposal on holographic coding solutions in the near future. This workshop intends to provide an overview of the key applications domains in holographic imaging, such as microscopy, tomography, printing and displays and collect more information on desired functionalities and requirements for associated coding solutions.

13:30-13:35 Welcome (Prof. Touradj Ebrahimi, EPFL)
About the speaker: Touradj Ebrahimi is professor at the Swiss Federal Institute of Technology in Lausanne (EPFL), working in teaching and research in multimedia signal processing. He is also Convener of the JPEG standardization committee, which has produced a family of standards that have revolutionized the world of imaging. He represents Switzerland as the head of its delegation to SC29 (the body that oversees MPEG and JPEG standardization committees), and he acted as the chairman of the SC29 Advisory Group on Management for many years until 2014.
13:35-13:45 Introduction (Dr. Kwan-Jung Oh, ETRI)
About the speaker: Kwan-Jung Oh received his M.S. and Ph.D. degrees in Information and Communications Engineering from the Gwangju Institute of Science and Technology (GIST), Gwangju, Rep. of Korea, in 2005 and 2010, respectively. He joined the Electronics and Telecommunications Research Institute (ETRI), Daejeon, Rep. of Korea in 2013, where he is currently a Senior Researcher with the Broadcasting and Media Research Laboratory. His research interests include 3-D image and video coding, immersive media, and holography.
13:45-14:15 Holographic printing: technologies and requirements (Dr. Jisoo Hong, KETI)
Holographic printing allows for recording and visualisation of digital holograms very high resolutions. It can be used to present digitally generated 3D content with a quality comparable to the analog holograms or to implement free-form holographic optical elements. In this presentation, holographic printing techniques and their associated requirements will be discussed.
Dr. Jisoo Hong received his PhD degree in electrical engineering from Seoul National University, Korea, in 2012. From 2004 to 2008, he was a senior research engineer with LG Electronics, Korea. In 2013, he was a postdoctoral researcher in the Department of Physics at USF, Tampa, Florida. Presently, he is a principal researcher with KETI (Korea Electronics Technology Institute), Korea. He is interested in 3D display techniques ranging from light field to holographic representation.
14:15-14:45 Holographic displays: technologies and requirements (Prof. Daping Chu, Univ. of Cambridge)
Abstract: The talk is aimed to provide insight in both the hardware and software technologies behind holographic displays such as large area displays and HMDs, the main use cases including large size and wide viewing angle 3D displays, present constrains on the display performance and finally also some requirements relevant for compression.
About the speaker: Professor Daping Chu is Director of CAPE (Centre for Advanced Photonics and Electronics) and Director of Centre for Photonic Devices and Sensors at University of Cambridge. His current research interests include phase-only spatial light modulators, AR/VR HMDs and HUDs, holography for future 3D displays and illuminations as well as optical telecom switches.
14:45-15:15 Technologies, applications and requirements for digital holographic microscopy (Dr. Yves Emery, Lynceetec)
Digital Holography Microscopes (DHM) are used routinely in many life and material sciences research labs, in pharma industry and for quality control on production lines. Their advantages and therefore the related technical challenges and requirements, in particular in term of data storage and processing will be illustrated through concrete application examples.
About the speaker: Yves Emery, born in 1966, graduated in Physics at Swiss Federal Institute of Technology of Lausanne (EPFL), holds a PhD in Physics from the Group of Applied Physics (GAP) of the University of Geneva, and a Business Administration Postgraduate certificate of the University of Lausanne (HEC-UNIL). He made his postdoctoral studies at Texas A&M University. His main fields of research are optics and lasers applied to medical, environment sensing, and metrology. He is presently CEO of Lyncée Tec SA.
15:40-16:10 Holographic tomography, technologies and interoperability requirements (Prof. Malgorzata Kujawinska, WUT)
Abstract: Holographic tomography is one of the booming applications in the holography domain. In this presentation the main technologies enabling holographic tomography will be discussed, as well as requirements that will be imposed on coding engines handling this type of holographic data.

16:10-16:35 Holographic data and source coding challenges (Prof. Peter Schelkens, VUB-imec)
Abstract: Compression of holographic data has received in recent years more attention. Nonetheless, image characteristics are significantly differing from natural images. Moreover, for specific applications huge resolution are required and complex-numbered data representations need to be supported. Hence, significant changes are required to classic image coding architectures to facilitate support of holographic data.
About the speaker: Peter Schelkens holds a professorship with the Department of Electronics and Informatics, Vrije Universiteit Brussel, Belgium and is a Research Group Leader at imec, Belgium. In 2013, he received an EU ERC Consolidator Grant focusing on digital holography.

16:35-17:00 Quality Assessment (Prof. Antonio Pinheiro, UBI)
Abstract: To validate holographic coding technologies, suitable evaluation methodologies need to be deployed. Classical methodologies are not straightforwardly applicable to holographic data. In this talk solutions and challenges for objective and subjective quality assessment of holographic data will be addressed.

He is a Portuguese delegate to the JPEG standardization committee, where he is currently the Communication Subgroup chair and is involved with the JPEG Pleno development.
17:00-17:30 Panel Discussion (Invited speakers)
Recently, the paper “JPEG Pleno: Providing Representation Interoperability for Holographic Applications and Devices” was published in the ETRI Journal (open access). This paper produced an excellent overview of current use cases, requirements and technological challenges.
