Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
High Dynamic Range (HDR) image and video technology aims at conveying the full range of perceptible shadow and highlight details with sufficient precision. HDR is regarded by many experts as the next evolution in digital media. However, industrial broadcasters have concerns regarding the bandwidth overhead that this new technology entails. While many consider that broadcasting HDR content would increase...
A large amount of computer graphics content is now regularly rendered in High Dynamic Range (HDR). The computational requirements of this are such that this rendering is typically done remotely. As the data requirements of HDR are large, compression is required if the resultant HDR frames are to be streamed efficiently to where they are required on existing ICT infrastructure. This paper investigates...
Due to the ever increasing commercial availability of High Dynamic Range (HDR) content and displays, backward compatibility of HDR content with Standard Dynamic Range displays is currently a topic of high importance. Over the years, a significant amount of Tone Mapping Operators (TMOs) have been proposed to adapt HDR content to the restricted capabilities of SDR displays. Among them, the Histogram...
This paper presents two approaches to coding HDR/WCG video, by modifying certain components of an HDR video processing chain developed recently in standards committees (the Joint Collaborative Team on Video Coding, or JCT-VC, of ITU|ISO/IEC), which is an HDR10 compliant system (the “anchor”). One approach, called FastVDO_ECHDR, differs from the anchor in two tools: the intermediate color representation,...
Linear multi-component transforms (MCTs) are commonly employed for enhancing the coding performance for the compression of natural color images. Popular MCTs such as the RGB to Y'CbCr transform are not optimized specifically for any given input image. Data-dependent transforms such as the Karhunen-Loève Transform (KLT) or the Optimal Spectral Transform (OST) optimize some analytical criteria (e.g...
While most health systems serve the majority of their citizens well, each has its challenges and gaps that lead to inadvertent marginalization of certain populations. The engagement of traditional stakeholders in health - policy makers, patients, health professionals, health administrators - to address these issues are necessary but insufficient if unconventional solutions are to be discovered. Use...
Health information technology (HIT) promises to modernize healthcare, lead to efficiencies and to reduce medical error. However, the literature has shown that if HIT is not designed and tested properly, systems such as electronic health records (EHRs) and personal health records (PHRs) may actually inadvertently introduce new types of errors that are termed technology-induced errors. Such error may...
Modern technology has so far been adopted into the various European health systems at different stages. This has lead to a number of recommendations from the EU at a national and at an EU level [1]. In Germany, a “law on safe communication and applications in healthcare” (so called eHealth-law) has been passed by the German government in December 2015 [2]. It aims to accelerate the introduction of...
The technological revolution of the 21st Century has been impressive and mind boggling. It has a major impact in all the fields, but probably one with a highest impact is health. If we connect the speed impact and transformation of the technology with the importance for society of wellness and health and the millennial vision of here and now, instant responses open tremendous opportunities for technology...
This paper presents an approach for automated estimation of human emotions from electroencephalogram data. The used features are principally the Hjorth parameters calculated for theta, alpha, beta and gamma bands taken from certain channels. The classification stage is support vector machine. Since the human emotions are modelled as combinations from physiological elements such as arousal, valence,...
Given its potential for more realistic rendering and enhanced user experience, High Dynamic Range (HDR) imaging is raising a lot of interest both in industry and academia. In this context, efficient representation and coding techniques are needed, as HDR video entails significantly higher raw data rate. In this paper, we present a temporally constrained content-adaptive Tone Mapping Operator (TMO)...
This paper presents the results of a subjective evaluation experiment, made to compare different HDR coding technologies, conducted at the recent ITU/ISO/IEC VCEG/ MPEG/JPEG Meeting in San Diego, CA, February 2016. A set of “anchor” streams, conforming to the HDR10 spec, was compared to a similar rate-matched set obtained using a method called “Reshaper”, which requires normative changes to the underlying...
From relatively unknown, just 5 years ago, High Dynamic Range (HDR) video is now having a major impact on most aspects of imaging. Although one of the five components of the specification for UHDTV, ITU-R Recommendation BT.2020 in 2012, it is only when it became apparent that HDR could help accelerate the slow penetration of 4K into the TV and home-cinema market, that HDR suddenly started to gain...
The new High Dynamic Range (HDR) technologies intend to increase the immersiveness and quality of experience of the observers thanks to much larger luminance and contrast characteristics. This increase of the amount of information requires the development of new sophisticated compression algorithms. Moreover, well-known objective quality metrics designed for Low Dynamic Range (LDR) systems may not...
