Keynote Speaker 1

Dr. David Tschumperlé (CNRS, France)
Title : From the development of open source software for image processing to the creation of algorithms to help artistic production

David Tschumperle, CNRS, France

Abstract:  I will describe the different steps that led me in almost 20 years to the development of the free software G'MIC. Today, G'MIC is used by hundreds of illustrators and photographers around the world to help them create their digital artworks. I will describe some of the research collaborations started with them that led to the creation of specific filters and tools to speed up the process of colorization or illumination of line art drawings, as well as to provide several hundred of color profiles at no cost to change the color mood of images.

Biography: David Tschumperlé is a CNRS researcher, working in the field of image processing since 1999. For more than 20 years, he strives to share his achievements by distributing open-source software and libraries to help people doing image processing tasks. He now focuses on designing tools for artistic images creation and computational photography. He leads the IMAGE team of the GREYC laboratory located in Caen.

Pr. Issei Fujishiro (Department of Information and Computer Science, Keio University, Japan)
Title: The Cyclopean Eye: Pinpointed Anamorphosis for Personal Stereoscopic Views

Pr Issei Fujishiro

Abstract: Inspired by the trick artworks of Hideyuki Nagai, a young Japanese artist, we have developed a simple naked-eye stereoscopic viewing system for personal use. It induces motion parallax through the orthogonal arrangement of two general-purpose display monitors and combining anamorphosis, known as monocular illusion expression, with tracking the viewer’s eyes. However, the stereoscopic effect perceived by the viewer can be degraded when using small display monitors due to binocular disparity. In this talk, I sketch our latest idea of pinpointing the anamorphosis effect by identifying the different degrees of contribution the two eyes make when recognizing the composition of a synthetic space. We have empirically proved that rather than detecting and tracking the dominant eye, the sense of presence is possibly improved by placing a so-called Cyclopean eye at a certain internal position between the two eyes to obtain the pinpointed anamorphosis. We report on a trial porting of this proposed approach to a commercially available laptop PC with a foldable display and present a few examples of immersive cyberworlds.

Biography: Issei Fujishiro is a full professor in the Department of Information and Computer Science, Faculty of Science and Technology, Keio University, Japan. He was a visiting professor of computer science at Stony Brook University, NY, USA, from 1994 to 1995. He received his Doctor of Science in Information Sciences from the University of Tokyo in 1988. His research interests are modeling paradigms and shape representations, applied visualization design and lifecycle management, and smart ambient media with multimodal displays. He has served on the editorial boards of several academic journals, including IEEE Transactions on Visualization and Computer Graphics (1999–2003 and 2018–2022) and Elsevier Computers & Graphics (2003–2013) and Journal of Visual Informatics (2016–present). He co-founded IEEE PacificVis in 2008, and has chaired more than 30 international conferences, including the conference chair for Cyberworlds 2013 and CG International 2017, a program co-chair for Cyberworlds 2019, and a paper co-chair for IEEE VIS 2018/2019 (SciVis). He is a currently appointed member of the Science Council of Japan and the president of the Visualization Society of Japan. He is an honorary member of the Institute of Image Electronics Engineers of Japan, a fellow of the Japan Federation of Engineering Societies and Information Processing Society of Japan, and a senior member of IEEE and ACM.


Keynote Speaker 3

Pr. Audun Josang (Department of Informatics, University of Oslo, Norway)
Title: Supply Chain Security and Mitigation Strategies

Pr. Audun Josang

Abstract: Supply chain attacks mean that attackers can infiltrate systems and networks through an external partner or vendor which has access or which supplies components with access to the company's systems and data. From a security perspective, the supply chains represent part of the attack surface. The dependence on long and complex supply chains has led to a dramatic increase in the attack surface of the typical business in recent years. Every entity that contributes to a supply chain has the opportunity to influence security further up the supply chain. The longer and more complex the supply chain is, the more difficult it is to get an overview of threats and vulnerabilities, and the more difficult it is to handle security incidents. This talk describes the challenge of managing security risks related to supply chain attacks and discusses possible mitigation strategies.

Biography: Audun Jøsang is Professor and head of the Research Group on Digital Security at the University of Oslo. Previously he was Associate Prof. at QUT in Australia, and worked in the telecommunications industry for Alcatel Telecom in Belgium and Telenor in Norway. Prof. Jøsang has a PhD in Information Security from NTNU where he also worked as Associate Prof. He has two Master's degrees; one in Information Security from Royal Holloway College, University of London, and the other in Telecommunications from NTH. He is a CISSP and CISM with broad expertise and experience in information security.


Keynote Speaker 4

Pr. Reinhold Scherer (University of Essex, UK)
Title: On coadaptive Brain-Computer Interfaces, Games and Virtual Reality

Arun Ross

Abstract: Spontaneous electroencephalogram (EEG)-based Brain-Computer interfaces (BCIs) enable their users to interact with external devices through thought alone, providing new ways of communication for people that cannot use conventional human-computer interaction or assistive technologies. However, intense performance fluctuations during BCI use and the inability of a large portion of users to get into control of the BCI remain the main obstacles towards deploying BCI technology in real-world scenarios. In this presentation, I will argue that EEG-based "plug-and-play" online coadaptive BCIs that automatically adapt or re-calculate model parameters on the fly help overcome the above issues. I will also present ideas on how BCI technology can be used to detect system errors in in Virtual Reality (VR), paving the way for the development of adaptive and self-corrective VR applications.

Biography: Reinhold Scherer is Professor in Brain-Computer Interfaces (BCI) and Neural Engineering (NE) at the School of Computer Science and Electronic engineering, University of Essex, Colchester, UK and co-director of the Essex BCI-NE laboratory. He received the M.Sc. and Ph.D degrees in computer science from Technische Universität Graz (TU Graz), Austria in 2001 and 2008, respectively, where he received the Habilitation (venia docendi) for applied computer science in 2016. From 2008 to 2010, he was postdoctoral researcher at the Department for Computer Science & Engineering, University of Washington, Seattle, USA. From 2010 to 2016 he was assistant professor and from 2016 to 2018 associate professor with the Institute for Neural Engineering, TU Graz. From 2011 to 2018 he was deputy director of the Institute of Neural Engineering. His primary research interests are in the areas of online brain-machine co-adaptation, statistical and adaptive signal processing, mobile brain and body imaging, and rehabilitation. Active research topics focus on gaining deeper insights into brain dynamics and mechanisms underlying motor and cognitive learning, with the goal of improving the interpretability of brain rhythms and thereby optimizing the performance of spontaneous EEG-based BCI interaction and rehabilitation protocols. He has published many scientific papers and holds one patent. He is Associate Editor for Scientific Reports, Frontiers in Neuroprosthetics and Brain-Computer Interfaces journal.
