“…Another possibility, which is the one we used in our experiments, is to have the participants rank the tone mapped images against a reference. Previous TMO evaluations that have used psychophysical experiments include work by [21], [22], [23], [24], [25], [26].…”

“…In 2005, Ledda et al [22] were the first to use an image displayed on an HDR monitor as a reference. In addition to evaluating six TMOs, the authors also introduced a new methodology for comparing images.…”

“…Another interesting fact is that the only experiment that was conducted using an HDR display as reference was [22] while the other evaluations had has reference the real scene or no reference at all. The experiments presented on this paper benefit from using an HDR display as reference and address HDR video tone-mapping with state-of-the-art TMOs.…”

Tone mapping operators (TMOs) allow the visual appearance of High Dynamic Range (HDR) video to be reproduced on Low Dynamic Range (LDR) displays. While several studies have been made to compare the performance of different TMOs on standard displays, there is only one preliminary study that take into account the characteristics of Small Screen Devices, common on mobile platforms. Due to the unique characteristics of mobile devices, the variety of viewing conditions where they are used, and the fact that they are becoming so widespread, it is important to identify what is the best method to deliver HDR video content to these devices. This paper presents an evaluation of HDR video using and HDR display as reference as well as six state-of-the-art HDR video tone mappers by conducting a psychophysical experiment where participants were asked to rank the tone mappers applied to different HDR video footage. A comparison was made between tone mapped HDR video footage shown on a tablet and an LCD display compared with the same HDR video footage shown on an HDR display. This study shows interesting results like the fact that for each display results obtained are different but the the preferred TMOs order remains the same.

“…Therefore, quality measurement techniques for TMOs can be based on comparisons of the reproduced result with the original scene (or with the original scene as reproduced by a special HDR display) [6,7]. For SAR data, no original appearance exists, and objective quality measurements for dynamic range reduction methods are currently not possible.…”

“…Yoshida et al [80] asked users to rank the accuracy of operators by comparing tonemapped images to the real scenes. Ledda et al [40] concluded that tonemapped images might not be similar enough to real scenes to obtain meaningful relations from operator comparisons. Instead, they ask users to compare the results of tonemapping operators to images on an HDR display, which they previously demonstrated [39] was an accurate depiction of real scenes.…”

Many real-world scenes contain a dynamic range that exceeds conventional display technology by several orders of magnitude. Through the combination of several existing technologies, new high dynamic range displays, capable of reproducing a range of intensities much closer to that of real environments, have been constructed. These benefits come at the cost of more optically complex devices; involving two image modulators, controlled in unison, to display images. We present several methods of rendering images to this new class of devices for reproducing photometrically accurate images. We discuss the process of calibrating a display, matching the response of the device with our ideal model. We then derive series of methods for efficiently displaying images, optimized for different criteria and evaluate them in a perceptual framework.iii
