Special Issue Information

Dear Colleagues,

High-dynamic range (HDR) imaging has been successfully researched for the last 30 years. Early algorithms are now integrated in widely, publicly distributed software. HDR displays are available on the market. However, there remain fundamental issues to solve. This Special Issue targets papers that bring these remaining issues and stimulating future trends to light.

We encourage submissions of original contributions to HDR imaging at large, and related areas. We invite papers on new ideas, presented in different formats: Theoretical papers, practice, experience, technological or research systems, and surveys. Papers will follow a peer review process. Only original papers presenting novel contributions will be considered. Extensions of previously accepted papers in conferences or workshops should justify additional content.

They could present solutions to any of the different stages of HDR imaging, such as acquisition, encoding, display, quality of experience, evaluation metrics, compression, transmission, tone mapping, editing, etc. They could address any supporting media: Image, video, lightfield, etc. Papers are also sought on novel contributions on practical solutions and new usages of HDR imaging, for instance, on how HDR imaging integrates new media and applications.

Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Imaging is an international peer-reviewed open access quarterly journal published by MDPI.

High dynamic range (HDR) imaging techniques are nowadays widely used in building research to capture luminances in the occupant field of view and investigate visual discomfort. This photographic technique also makes it possible to map sky luminances. Such images can be used for illuminating virtual scenes; the technique is called image-based lighting (IBL). This paper presents a work investigating IBL in a lighting quality research context for accelerating the development of appearance-driven performance indicators. Simulations were carried out using Radiance software. The ability of IBL to accurately predict indoor luminances is discussed by comparison with luminances from HDR photographs and luminances predicted by simulation in modeling the sky in several other more traditional ways. The present study confirms previous observations that IBL leads to similar luminance values than far less laborious simulations in which the sky is modeled based on outdoor illuminance measurements. IBL and these last methods minimize differences with HDR photographs in comparison to sky modeling not based on outdoor measurements. Full article

Title: Application of high-dynamic range imaging techniques in architecture: a step toward high-quality daylit interiors?
Author: Coralie Cauwerts
Abstract: High dynamic range (HDR) imaging techniques are nowadays widely used in building research to capture luminances in the occupant field of view. But it can also be used to map sky luminances. Image-based lighting (IBL) is a method of illuminating virtual scenes using such images. The two main reasons for running IBL simulations rather than traditional physically-based renderings (PBR) are that (1) IBL simulations could increase the accuracy of lighting simulations as real luminous distributions of the sky are used rather than mathematical models (2) the surrounding buildings and vegetation are easily incorporated in the simulation as they can be part of the HDR picture. When investigating perceived atmosphere of daylit interiors by the use of renderings, these improvements are not negligible.

This paper aims at discussing opportunities of HDR imaging techniques for predicting light quality in buildings. It will first introduce the context in defining lighting quality, explaining the interest of luminance maps for studying risks of glare and highlighting the need for developing appearance-driven performance indicators to assess the aesthetic dimension of architecture. The core of the paper will consist in a comparison of luminance maps acquired in real world using HDR photography and luminance maps computed with the Radiance lighting simulation tool using IBL or PBR techniques. The acquisition of sky luminances using HDR photography will be described and discussed. The paper will also address the issue of displaying HDR content for studying perceptions (which display device? which tone-mapping operator?).
