Motivation and Objectives
With the advancement of computing technology, a large amount of graphic and high-dynamic range imaging (HDRI) data are deployed in various applications, such as digital entertainment, Internet, scientific visualization, computer-aided design, virtual reality, telepresence, etc. These data delivery pipeline includes by rendering, compression, watermarking, transmission, and so on. Since humans are the ultimate consumers of the majority of (if not all) produced graphic and HDRI data, and as a result of evolution, the human perceptual system has developed unique physiological and psychological mechanisms in processing and understanding of visual information, it would be beneficial to incorporate visual perception-based criteria in the design and optimization of the related design and processes. Additionally, since these processes may introduce visual artifacts and degrade the delivered quality, it is important to evaluate the visual artifacts introduced into the original visual content, and to make the relevant decisions in graphic/HDRI algorithms and systems. Objective quality metrics which correlate well with the human visual perception need to be designed to enhance quantitative analysis.
This special session therefore seeks submissions that advance knowledge and represent the latest technology developments in the area of perceptual graphics, transmission and rendering, especially the Quality of Experience (QoE) for these processes, as well as innovative applications and system integration.
