TITLE: Holographic visualization: signal processing and technological
challenges

ABSTRACT:3D visualization has received increased attention in recent
years, significantly boosted by the advent of new AR/VR/XR display
devices and the metaverse paradigm. However, current display solutions
based on – for example – stereoscopic or light field representations
still depict significant shortcomings regarding, e.g., supported viewing
angle and eye accommodation. Using the holographic modality instead
might bring a solution to the encountered problems. Though the term
holography is often misused because of marketing reasons – the name is
often linked with ideal 3D visualization solutions – real holography
uses a wave-based light propagation model instead of the ray-based
models used for regular 3D visualization systems.
Notwithstanding the big promises of holography and the evolution of the
underlying supporting technologies, the challenges of bringing this
technology to the professional and consumer markets are still huge.
This talk will focus on the challenges related to the generation,
processing, coding, and quality assessment of holographic content in
combination with the underlying computation, optoelectronic, optical and
photonics hardware. In this context, also the status of JPEG Pleno,
currently defining the first international standard for coding of
holographic content, will be discussed.

BIO: Peter Schelkens received his degree in electronic engineering in
VLSI-design from the Industriële Hogeschool Antwerpen- Mechelen (IHAM),
Campus Mechelen, in 1991. After that, he obtained an electrical
engineering degree (MSc) in applied physics (1994), a biomedical
engineering postgraduate degree with a specialization in medical physics
(1995), and, finally, a Ph.D. degree in applied sciences (2001) from the
Vrije Universiteit Brussel (VUB).
Peter Schelkens currently holds a professorship at the Department of
Electronics and Informatics (ETRO) at the Vrije Universiteit Brussel
(VUB), Belgium. He is also affiliated with the Interuniversity Institute
for Microelectronics (imec) in Leuven, Belgium, where he is currently
active as principal investigator.
The research interests of Peter Schelkens are situated in the field of
multidimensional signal processing encompassing the representation,
communication, security, rendering and quality assessment of these
signals. In 2013 he was awarded an EU ERC Consolidator Grant focusing on
digital holography.
Peter Schelkens has published over 300 papers in journals and conference
proceedings, and he holds several patents. His team participates in the
ISO/IEC JTC1 /SC 29/WG 1 (JPEG) standardization activities. Since 2018,
he has been rapporteur/chair of the JPEG Coding, Test and Quality
Subgroup and he is actively involved in coordinating the JPEG PLENO
standardization activity. He is currently also convenor of ISO/IEC JTC1
/SC 29/AG 4 coordinating the collaboration between JPEG and MPEG
communities.
Peter Schelkens is associate editor of Elsevier Signal Processing: Image
Communication, AOP JPhys Photonics, Springer Journal of Quality and User
Experience, and Light: Advanced Manufacturing. He has been previously
associate editor of IEEE Transactions on Circuits and Systems for Video
Technology.
