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.

A perceptual framework for contrast processing of high dynamic range images
TL;DR: To predict the visibility of suprathreshold contrast, it is shown that a complex contrast compression operation, which preserves textures of small contrast, is reduced to a linear scaling in the proposed visual response space.

LogLuv encoding for full-gamut, high-dynamic range images
TL;DR: This paper proposes a compact encoding suitable for the transfer, manipulation, and storage of high dynamic range color images, and encodes color pixels as log luminance values and CIE (u',v') chromaticity coordinates.

Backward compatible high dynamic range MPEG video compression
TL;DR: A compact reconstruction function is introduced that is used to decompose an HDR video stream into a residual stream and a standard LDR stream, which can be played on existing MPEG decoders, such as DVD players.

Extending Quality Metrics to Full Luminance Range Images
TL;DR: To estimate quality of images shown on bright displays, this work proposes a straightforward extension to the popular quality metrics, such as PSNR and SSIM, that makes them capable of handling all luminance levels visible to the human eye without altering their results for typical CRT display Luminance levels.
