Ex uno plures: how to construct high-speed movies of collapsing cavitation bubbles from a single image

Mohamed Farhat, Davide Bernardo Preso, Armand Baptiste Sieber

The time-resolved visualization of the dynamics of a cavitation bubble usually requires the use of expensive high-speed cameras, which often provide a limited spatial resolution. In the present study, we propose an alternative to these high-speed imaging t ...

Multi-object spectroscopic operations with the Sloan Digital Sky Survey V

Ricardo Jorge Araùjo Pereira, Luzius Gregor Kronig, Loïc Grossen

The Sloan Digital Sky Survey V (SDSS-V) is an all-sky spectroscopic survey of more than 6 million objects, designed to decode the history of the Milky Way, reveal the inner workings of stars, investigate the origin of solar systems, and track the growth of ...

High dynamic range image sharing with privacy protection

Touradj Ebrahimi, Evgeniy Upenik, Pol Fernandez Marti

Sharing pictures has become a very popular practice among consumers. Most recent cameras, displays, and smartphones can capture and display images in high dynamic range and wide colour gamut, contributing to an increase of this type of content. It is a wel ...

Embedded Polarizing Filters to Separate Diffuse and Specular Reflection

Laurent Valentin Jospin, Adam James Scholefield, Gilles Baechler

Polarizing filters provide a powerful way to separate diffuse and specular reflection; however, traditional methods rely on several captures and require proper alignment of the filters. Recently, camera manufacturers have proposed to embed polarizing micro ...

HDR Images for Glare Evaluation: Comparison Between DSLR Cameras, an Absolute Calibrated Luminance Camera and a Spot Luminance Meter

Marilyne Andersen, Jan Wienold, Peter Hansen

User calibrated digital single-lens reflex (DSLR) cameras are being used in visual comfort and especially for glare evaluations as affordable alternatives to high-end luminance cameras calibrated by the manufacturer itself. While the typical way for a user ...

Wide-Baseline Foreground Object Interpolation Using Silhouette Shape Prior

Pascal Frossard, Christophe De Vleeschouwer, Thomas Maugey

We consider the synthesis of intermediate views of an object captured by two widely spaced and calibrated cameras. This problem is challenging because foreshortening effects and occlusions induce significant differences between the reference images when th ...

Interconnected Network of Cameras

Pierre Vandergheynst, Alexandre Schmid, Yusuf Leblebici, Mahdad Hosseini Kamal, Hossein Afshari

The real-time development of multi-camera systems is a great challenge. Synchronization and large data rates of the cameras adds to the complexity of these systems as well. The complexity of such system also increases as the number of their incorporating c ...

FACT - The First G-APD Cherenkov Telescope (first results)

Werner Lustermann, Mathieu Ribordy, Thomas Günther Bretz

In October 2011, the first air-Cherenkov telescope utilizing Geiger-mode avalanche photodiodes commenced operations. The silicon-based devices display several advantages compared to classical photomultiplier tubes allowing for a more compact camera design ...
