“…As the 3D display technologies are currently being actively developed, there is no similar stateof-the-art dissemination of knowledge for tone mapping on light field displays. To the best of the authors' knowledge, the only currently available papers on related topics are about tone mapping for VR [34], panoramic images [35], stereo images [36], or multi-view displays [37].…”

At the time of writing this paper, light field visualization has entered the professional environments in the industry and has also become commercially available. It is not yet present on the consumer market, however, and its widespread emergence is expected in the following decade, with affordable end user devices and a vast variety of applications and contents. The successful integration of this technology into people's everyday lives essentially depends on the visualization quality, which is achieved through excellence in terms of the key performance indicators of the display system and the content it visualizes. In this paper, the key performance indicators of light field visualization for both display and content are reviewed. Beyond providing a comprehensive review of the vital parameters of visualization quality, this paper discusses the ongoing and future relevant research efforts, demonstrates the practical uses of the technology, highlights certain dependencies between the indicators, and addresses issues of perceived quality with regard to the lack of compliance with the requirements and visual thresholds.

“…Compared to the conventional low dynamic range (LDR) technologies, HDR displays offer visual experience with more realism and immersion. While HDR is rapidly spreading among the instances of 2D visualization, it is also approaching the most novel 3D technologies as well, such as stereoscopic 3D (Yang et al 2012), virtual reality (Najaf-Zadeh et al 2017), multi-view displays (Wang et al 2017), and light field displays (Doronin and Barsi 2018). Every advance we see today in research efforts and display developments bring closer a future where HDR is the default screen format.…”

The effect of labeling on the perceived quality of HDR video transmission

At the time of this paper, high dynamic range (HDR) visualization has already emerged in both the industry and the commercial sector, with HDR displays already present on the consumer market and the technology marching towards the goal of becoming the de facto format of multimedia. HDR is thus often looked at and praised as the next logical step in the evolution of audiovisual entertainment. However, there is no such thing as a single, universal HDR standard, and the competing market projects a future with even more diversity in format specifications, display capabilities and content characteristics. As the competitors attempt to surpass each other and obtain a bigger share of the global market, they inevitably bombard the potential customers and users with brief but effective labels that reflect excellence and superior quality. In this paper, the cognitive effect of such labels is investigated. As home video entertainment is possibly the most numerous instance of the future usage of this visualization technology, video streaming is particularly addressed. Since real-time video transmission services are bound to suffer playback interruptions upon insufficient data rates and uncompensated drops in the available bandwidth, stalling events experienced in conventional multimedia streaming shall apply to HDR video as well. The paper presents four separate experiments, studying how the cognitive bias caused by the labeling effect influences the perception of HDR quality aspects and stalling events, and how the cognitive load varies for stalling detection thresholds between conventional and HDR visualization.
