TLDR
The emergence of HDR is seen as an important step towards improving the visual quality of experience (QoE) of the end users, but it comes with its own set of challenges including capture, storage, processing, display, and so on.Abstract:
Traditional capture and display devices can only support a limited dynamic range (contrast) and color gamut given the hardware limitations. As a result, the real physical luminance present in a natural scene cannot be captured by these. However, with the recent advancements in the related software and hardware technologies, it is now possible to capture or reproduce higher contrast and luminance ranges. Such scene-referred visual signals are known as high dynamic range (HDR) signals. They are visually more appealing because they can represent the dynamic range of the visual stimuli present in the real world more accurately. Not surprisingly, the emergence of HDR is seen as an important step towards improving the visual quality of experience (QoE) of the end users. However, HDR comes with its own set of challenges including capture, storage, processing, display, and so on. This chapter focuses on some of those issues from a QoE viewpoint.read more

Investigation of relationships between changes in EEG features and subjective quality of HDR images
TL;DR: Investigating the relationships between changes in EEG features and subjective quality test scores for High Dynamic Range (HDR) images viewed with a mobile device suggests that increases in the degree of coupling are associated with decreases in HDR quality and suggests that in the HDR image QoE assessment, human emotions play a significant role.

Impact of tone-mapping operators and viewing devices on visual quality of experience
TL;DR: Preliminary results show that small screen displays (SSDs) have an impact on the performance of TMOs compared to computer displays, and the larger the mobile resolution, the better the subjective results.

Premium Hdr: The Impact of a Singleword on the Quality of Experience of Hdr Video
TL;DR: This paper investigates the labeling effect on HDR video QoE by carrying out a series of subjective tests where test participants compared unimpaired HDR videos and found that one of the stimuli in the paired comparison was identified as Premium HDR.

Impact of tone mapping in high dynamic range image compression
TL;DR: The study reveals that the perceptual quality of the decompressed HDR signal is dependent on the tone mapping method employed, and presents the results and analysis of a comprehensive subjective study in which the decompression HDR images were displayed on an HDR display.

HDR image compression using optimized tone mapping model
TL;DR: Not only the quality of the HDRI but also the one of LDRI are improved, compared with a state of the art in conventional HDRI compression.

Real-Time Algorithms for High Dynamic Range Video
TL;DR: Algorithms for these steps that allow the creation of HDR video in real-time are covered that are robust to the large brightness difference between the images of an exposure sequence, and tone mapped to the displayable range of the output device.
