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.

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.

Evaluation of tone mapping operators using a High Dynamic Range display

TL;DR: A series of psychophysical experiments are presented to validate six frequently used tone mapping operators against linearly mapped High Dynamic Range (HDR) scenes displayed on a novel HDR device and to determine the participants' impressions of the images produced compared to what is visible on a high contrast ratio display.
