Multi-Camera Platform for Panoramic Real-Time HDR Video Construction and Rendering

Yusuf Leblebici, Vladan Popovic, Kerem Seyid, Ömer Cogal, Eliéva Arlette Pignat

High dynamic range (HDR) images are usually obtained by capturing several images of the scene at different exposures. Previous HDR video techniques adopted the same principle by stacking HDR frames in time domain. We designed a new multi-camera platform wh ...

The Dynamics of Shadow: Architecture of Natural Light in Extreme Latitudes

Marilyne Andersen, Mandana Sarey Khanie, María Lovísa Ámundadóttir, Siobhan Francois Rockcastle

While architecture is composed of static structural elements, daylit space is perceived as a dynamic play of light and shadow – ephemeral qualities that add depth, texture, and movement to spatial composition. Our perception of architecture is greatly impa ...

Visual attention in LDR and HDR images

Touradj Ebrahimi, Philippe Hanhart, Hiromi Nemoto

Recent advances in high dynamic range (HDR) capturing and display technologies attracted a lot of interest to HDR imaging. Many issues that are considered as being resolved for conventional low dynamic range (LDR) images pose new challenges in HDR context. ...

Crowdsourcing evaluation of high dynamic range compression

Touradj Ebrahimi, Philippe Hanhart

Crowdsourcing is becoming a popular cost effective alternative to lab-based evaluations for subjective quality assessment. However, crowd-based evaluations are constrained by the limited availability of display devices used by typical online workers, which ...

Evaluation of privacy in high dynamic range video sequences

Touradj Ebrahimi, Martin Rerabek, Lin Yuan

The ability of high dynamic range (HDR) to capture details in environments with high contrast has a significant impact on privacy in video surveillance. However, the extent to which HDR imaging affects privacy, when compared to a typical low dynamic range ...

Use of a multilayer snow model to assess grazing conditions for reindeer

Michael Lehning

High-density snow layers deteriorate grazing conditions for reindeer during winter. We compare two different methods for identifying past winters with difficult grazing conditions for reindeer in Kautokeino, northern Norway. A long-term climate analysis ba ...

Influence of Context and Content on Tone-mapping Operators

Touradj Ebrahimi

High Dynamic Range (HDR) imaging is one of the technologies that are changing photo, TV, and film industries. The popularity and full public adoption of HDR content is however hindered by the lack of standards in evaluation of quality, file formats, and co ...
