Learned Compressive Representations for Single-Photon 3D Imaging

Edoardo Charbon, Claudio Bruschini, Andrei Ardelean, Mohit Gupta

Single-photon 3D cameras can record the time-of-arrival of billions of photons per second with picosecond accuracy. One common approach to summarize the photon data stream is to build a per-pixel timestamp histogram, resulting in a 3D histogram tensor that ...

Ray-tracing MRT and human thermophysiology model combination for local discomfort prediction

Dolaana Khovalyg, Arnab Chatterjee, Mohamad Rida

Thermal comfort and discomfort based on the local sensation of different body parts have been an important development in thermal comfort studies from the past decade. The human thermophysiology model can be a handy tool to predict local skin and core temp ...

Automated Daylighting Control System based on Sky Luminance Monitoring and Lighting Computing

Yujie Wu

Sufficient daylight exposure contributes to occupants' productivity and health in buildings. However, excessive daylight ingress induces discomfort glare and increases the cooling load in warm seasons. The performance of manual shading systems is limited b ...

Impact of dynamic lighting control on light exposure, visual comfort and alertness in office users

Jean-Louis Scartezzini, Mirjam Münch, Ali Motamed, Marta Benedetti, Lenka Maierova

The lighting environment at indoor workplaces is important not only to provide vision and visual comfort, but also for light's direct influence on human physiology, cognitive performance and mood. The purpose of this ongoing study is to investigate the imp ...

Copper Bipyridyl Redox Mediators for High Performance Dye-Sensitized Solar Cells

Yasemin Saygili

Photovoltaic (PV) technologies attract a lot of attention as a result of the increasing energy demand and environmental concerns stemming from the conventional energy resources. Accordingly, the power conversion efficiency (PCE) values of various solar ene ...

Learning to Reconstruct Texture-less Deformable Surfaces from a Single View

Pascal Fua, Mathieu Salzmann, Jan Bednarík

Recent years have seen the development of mature solutions for reconstructing deformable surfaces from a single image, provided that they are relatively well-textured. By contrast, recovering the 3D shape of texture-less surfaces remains an open problem, a ...

Dye-sensitized solar cells for efficient power generation under ambient lighting

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Paul Liska, Fabrizio Giordano, Ulf Anders Hagfeldt, Joël Teuscher, Xiaoyu Zhang, Yasemin Saygili, Marina Freitag

Solar cells that operate efficiently under indoor lighting are of great practical interest as they can serve as electric power sources for portable electronics and devices for wireless sensor networks or the Internet of Things. Here, we demonstrate a dye-s ...

Visible light-emitting host-guest electrochemical cells using cyanine dyes

Frank Nüesch, Roland Hany, Jakob Heier, Lei Wang, Beat Ruhstaller, Surendra Babu Anantharaman

Light-emitting electrochemical cells (LECs) can be fabricated as a single emissive organic/salt layer sandwiched between two electrodes, offering cost-effective next generation signage and lighting applications. Cyanine dyes are especially attractive to ex ...

3D geometry recovery from structured light system

Kévin Marc Jean Decoster

3D scanning is a technique that permits to recover the pixel depth and thus, the three-dimensional shape of an object. This technique is well known since about 25 years ago, but we have seen it coming back recently due to the rapid progress in image proces ...

Path-space Motion Estimation and Decomposition for Robust Animation Filtering

Wenzel Alban Jakob

Renderings of animation sequences with physics-based Monte Carlo light transport simulations are exceedingly costly to generate frame-by-frame, yet much of this computation is highly redundant due to the strong coherence in space, time and among samples. A ...
