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

***********************************

Ear recognition is an active area of research within the biometric
community. However, the work in this field has long focused on maximizing
raw recognition performance, while other aspects critical for the
deployment of biometrics recognition techniques in practice have largely
been ignored. One such example is demographic bias. Modern ear
recognition approaches are not only expected to be highly efficient when
recognizing individuals, but also to be equally fair in their decisions,
regardless of the demographic characteristics of the subjects, e.g.,
gender or ethnicity. The 2023 Unconstrained Ear Recognition Challenge
will, therefore, investigate the performance as well as demographic bias
of existing ear recognition solutions and promote research into
bias-mitigation mechanisms that have minimal impact on the recognition
performance.

Understanding demographic bias is important because it can help to
identify and mitigate inaccuracies and errors in biometric systems,
prevent the development of discriminatory systems, and even inform the
public policies and regulations related to biometric systems. Research
related to demographic bias in ear recognition techniques can help
promote the development of more accurate, fair, and just ear recognition
systems that are less likely to produce errors or false positives for
certain groups of people and protect individual's rights and interests.

To promote research in the bias-aware ear recognition, the Unconstrained
Ear Recognition Challenge (UERC) 2023 will bring together researchers
working in the field of ear recognition and benchmark existing and new
algorithms on a common dataset and under a predefined experimental protocol.

*** Execution ***
UERC 2023 will be organized as a two-track competition, where each track
will be focused on one specific goal. Participants will be free to enter
only a single track or compete in both. For each track, a dataset,
evaluation tool written in Python, and baseline models in Python will be
made available. A detailed description of the two tracks is given below:

Track 1: Fair Ear Recognition. The first UERC 2023 evaluation track will
collect ear recognition models and score their performance on ear images
captured in unconstrained environments. Here, the performance indicators
will include both, a measure of recognition performance as well as an
estimate of the exhibited demographic bias. Both recognition and bias
scores will contribute to the overall ranking. Participants will be free
to develop any type of model to maximize performance, while minimizing
bias. The final submission for this track will include a working
solution (source code or compiled binary), which the organizers will run
to evaluate the performance on a sequestered test data.

Track 2: Bias Mitigation. The second UERC 2023 track will address bias
mitigation strategies explicitly. Here, a baseline ResNet model (written
in Python) will be made available to the participants and the goal will
be to design bias mitigation schemes that reduce the initial bias of the
models without adversely affecting performance. Such schemes may include
additional model blocks and network components, normalization layers,
knowledge infusion mechanisms, score normalization procedures, image
preprocessing approaches and any other solution capable of reducing bias
of the predefined base model. Similarly to the first track, participants
will have to submit a working solution that the organizers will evaluate
on the sequestered test data.

*** Summary paper and co-authorship ***
The results of UERC 2023 will be published in the IJCB conference paper
authored jointly by all participants of the challenge.

*********************************************************************

CSS is a FedCSIS track aiming at integrating and creating synergy
between FedCSIS technical sessions which thematically subscribe to more
technical (or applicable) aspects of computer science and related
disciplines. The CSS track spans themes ranging from hardware issues
close to the discipline of computer engineering via software issues
tackled by the theory and applications of computer science, and to
communication issues of interest to distributed, smart, multimedia and
network systems.

The track is oriented on the research where the computer science meets
the real world problems, real constraints, model objectives, etc.
However the scope is not limited to applications, we all know that all
of them were born from the innovative theory developed in laboratory. We
want to show the fusion of these two worlds. Therefore one of the goals
for the track is to show how the idea is transformed into application,
since the history of modern science show that most of successful
research experiments had their continuation in real world. CSS track is
going to give an international panel where researchers will have a
chance to promote their recent advances in applied computer science both
from theoretical and practical side.
