The Heliodome project: an innovative approach in assessing solar-optical properties of light-redirecting materials in combination with sun course simulations

The Heliodome is a new type of video-based goniophotometer to measure materials and coatings intended to be used for advanced fenestration technologies or energy-efficient luminaires. Using calibrated digital cameras combined with a light projecting surfac ...

Retexturing in the Presence of Complex Illumination and Occlusions

Pascal Fua, Vincent Lepetit, Julien Pilet

We present a non-rigid registration technique that achieves spatial, photometric, and visibility accuracy. It lets us photo-realistically augment 3D deformable surfaces under complex illumination conditions and in spite of severe occlusions. There are many ...

Effects of alpine hydropower operations on primary production in a downstream lake

Alfred Johny Wüest, Beat Mueller, Martin Schmid

During the past century, the construction of hydropower dams in the watershed of Lake Brienz has significantly altered the dynamics of turbidity, which has important implications for lake productivity. To assess these effects, we measured in situ carbon as ...

Influence of shot noise on phase measurement accuracy in digital holographic microscopy

Christian Depeursinge, Tristan Colomb, Benjamin Rappaz, Pierre Marquet, Jonas Kühn, Florian Charrière

Digital Holographic Microscopy (DHM) is a single shot interferometric technique, which provides quantitative phase images with subwavelength axial accuracy. A short hologram acquisition time (down to microseconds), allows DHM to offer a reduced sensitivity ...

Light and temperature effects on Sr/Ca and Mg/Ca ratios in the scleractinian coral Acropora sp.

Anders Meibom

This study was designed to investigate the effect of light and temperature on Sr/Ca and Mg/Ca ratios in the skeleton of the coral Acropora sp. for the purpose of evaluating temperature proxies for paleoceanographic applications. In the first experiment, co ...

Face Detection and Verification using Local Binary Patterns

Yann Rodriguez

This thesis proposes a robust Automatic Face Verification (AFV) system using Local Binary Patterns (LBP). AFV is mainly composed of two modules: Face Detection (FD) and Face Verification (FV). The purpose of FD is to determine whether there are any face in ...
