The emergence of high dynamic range (HDR) is widely seen as an important step toward improving the quality of experience (QoE) of the end users. The concept of HDR QoE is, nonetheless, multi-faceted and comprises of dimensions such as immersiveness, perceptual fidelity, naturalness, etc. These dimensions are prone to be affected during the processing of HDR videos along the delivery chain and as a result affect the QoE of the end user. Thus, this chapter first identifies few key dimensions (components) in HDR QoE and then discusses the impact of HDR processing on few of them. In particular, we find that operations such as tone mapping (and inverse tone mapping) can alter the artistic intent of HDR content, and thus need to be considered in the design and development of HDR video processing algorithms. © 2016 Elsevier Ltd All rights reserved.
