TLDR
It is found that subjects experienced minimal visual fatigue, and also found statistically significant differences in preferred display settings under different ambient lighting conditions.Abstract:
Recent high dynamic range (HDR) display devices provide significantly greater output brightness and dynamic range compared to conventional display technology. A possible concern for the extended use of HDR displays is the potential to cause visual fatigue. Furthermore, ambient illumination has a significant effect on the perception of the imagery displayed, and its impact on user preferences for brightness and contrast must be understood.In our work we examine these issues by conducting two user studies. In each study, subjects watched video content on an HDR display in several different ambient illumination environments, and were asked to adjust the brightness and black level of the display to their preference. Subjects were also given questionnaires to document their observations and subjective preferences as well as any visual fatigue they may have experienced. We found that subjects experienced minimal visual fatigue, and also found statistically significant differences in preferred display settings under different ambient lighting conditions.read more

Deep HDR Imaging via A Non-Local Network
TL;DR: This study presents a novel deep framework, termed NHDRRnet, which adopts an alternative direction and attempts to remove ghosting artifacts by exploiting the non-local correlation in inputs and incorporates a triple-pass residual module to capture more powerful local features, which proves to be effective in further boosting the performance.

Method and apparatus for image data transformation
TL;DR: In this article, a sigmoidal transfer function is used to control min-tone contrast in the image data for display on a target display in a way that substantially preserves the creative intent embodied in the original image data.

A reassessment of the simultaneous dynamic range of the human visual system
Timo Kunkel,Erik Reinhard +1 more
TL;DR: The findings show that the human visual system is capable of distinguishing contrasts over a range of 3.7 log units under specific viewing conditions, thereby accounting for the differences reported in the literature and providing guidance for display design.

Photographic tone reproduction for digital images
TL;DR: The work presented in this paper leverages the time-tested techniques of photographic practice to develop a new tone reproduction operator and uses and extends the techniques developed by Ansel Adams to deal with digital images.

The statistics of natural images
TL;DR: Recently, there has been a resurgence of interest in the properties of natural images as mentioned in this paper, which can be viewed as satisfying certain "design criteria" such as invariance to scale.

Photographic tone reproduction for digital images
TL;DR: In this article, the tone reproduction problem is also considered, which maps the potentially high dynamic range of real world luminances to the low dynamic ranges of the photographic print, which is a classic photographic task.
