Visual communications with 6 Degrees of Freedom
Organizers: Francesca De Simone (CWI), Laura Toni (UCL)
Recent advances in 3D capturing technologies and visualization techniques, such as those enabling Virtual and Augmented Reality (VR and AR), are paving the way towards the deployment of visual communications that provide six Degrees of Freedom (6DoF) viewing capabilities to the user.
In a communication framework with 6DoF, the user can freely navigate the scene, changing her/his viewpoint, and spatially interact with the visual signals. Applications exploiting such scenario are of interest in a broad range of fields, from art and entertainment, to medicine and engineering. Thus, the key enabling technologies for these applications are receiving a lot of attention from main technological innovation players, both in academic and industrial communities.
In order to deploy visual communications with 6DoF, many research challenges need to be addressed across the whole signal processing chain: from the capture and representation of the new visual signals involved, namely dynamic and static volumetric signals, 3D models, etc; to their efficient storage and distribution; as well as their rendering via head mounted displays for VR and AR or classical mobile and desktop displays allowing for advanced interaction modalities. Finally, departing from the classical frame-based media consumption, the new modalities involved in 6DoF visual interactions raise new research questions concerning user’s visual perception and Quality of Experience (QoE) at large.
This special session aims at fostering discussions among the EUVIP community about the latest advances on technologies enabling visual communications with 6DoF. Topics of interest will include (being not limited to):
Contrast and its Role in Image and Video Quality Assessment
Organizers: Seyed Ali Amirshahi (NTNU) and Marius Pedersen (NTNU)
When studying the human visual system one of the most important topic is contrast and how it should be considered when it come to its use in image processing. Over the years different studies have tried to address topics such as contrast evaluation, contrast enhancement, and contrast modeling. While achromatic contrast sensitivity has been studied in detail little attention has been paid on chromatic contrast sensitivity. This special session aims to provide a platform for showcasing the theoretical and applied research advancements in this field of study. We aim to explore recent methods, challenges, and possible opportunities in this research domain. The topic of contrast and its effect on image and video quality is of special interest in fields such as medical imaging, video surveillance, remote sensing, underwater imaging, image forensics, intelligent transport systems, digital cinema, visual cultural heritage data, among others. While a large number of studies have focused on evaluating the quality of images and videos the same attention has been paid to the role of different properties such as contrast affcting the quality. Original and unpublished work is invited to be submitted in the special session. Topics of interest will include (being not limited to):
Intelligent Methods and Artificial Intelligence for Biomedical Imaging Systems
Organizers: Daniele Bibbo (Roma Tre), Jan Kubicek (VSB), Marius Pedersen (VSB), and Vladimir Kasik (VSB)
Recent technological trends in the medical informatics and biomedical engineering allow for development of complex intelligent biomedical systems including clinical computer-based decision support systems, medical knowledge acquisition, medical imaging, and computational intelligence in the biomedicine. Artificial intelligence has a significant impact on a field of the biomedicine, and such systems can be implemented for solving real-world applications based on the machine learning, neural computing, expert systems, genetic algorithms and others. Special section IMAIBIS 2019 provides a unique forum for researchers to discuss recent trends of novel aspects of the biomedical intelligent imaging systems. We invite researchers to contribute original research articles, as well as papers describing future directions of the biomedical intelligent imaging systems. Acceptance will be based on the quality, originality, and practical value of the work. Topics of the special section include, but are not limited to:
