Simulating occupant presence and behaviour in buildings

Various factors play a part in the energy consumption of a building : its physical properties, the equipment installed for its functioning (the heating, ventilation and air-conditioning system, auxiliary production of electricity or hot water), the outdoor ...

Optimisation of Buildings Daylight Availability

Jérôme Henri Kämpf, Darren Robinson, Marylène Montavon

Many researchers have the goal of improving buildings daylight availability in order to decrease the HVAC energy intake. Indeed by achieving/identifying sustainable urban forms and their design concepts, the benefits of the solar radiation can be of threef ...

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 ...

Modelling Complex Fenestration Systems

Jean-Louis Scartezzini, Anothai Thanachareonkit

Complex Fenestration Systems (CFS) are widely studied to help redirecting daylight into a room in order to optimise its luminous properties. Daylighting designers and researchers usually employ physical and virtual models to assess their daylighting perfor ...

Classifying Materials in the Real World

Barbara Caputo

Classifying materials from their appearance is challenging. Impressive results have been obtained under varying illumination and pose conditions. Still, the effect of scale variations and the possibility to generalize across different material samples are ...

A field investigation of the intermediate light switching by users

David Lindelöf, Nicolas Morel

This paper describes how data collected during a continuously running data acquisition program on the LESO building in Lausanne, Switzerland, was used to measure the intermediate light switch probability by users as a function of current illuminance levels ...

Active Shape Models Using Local Binary Patterns

Sébastien Marcel, Jean Keomany

This report addresses the problem of locating facial features in images of frontal faces taken under different lighting conditions. The well-known Active Shape Model method proposed by Cootes {\it et al.} is extended in order to improve its robustness to i ...

Robust-to-Illumination Face Localisation using Active Shape Models and Local Binary Patterns

Sébastien Marcel, Yann Rodriguez, Jean Keomany

This paper addresses the problem of locating facial features in images of frontal faces taken under different lighting conditions. The well-known Active Shape Model method proposed by Cootes {\it et al.} is extended to improve its robustness to illuminatio ...

Face Pose Estimation using a Tree of Boosted Classifiers

Jean-Philippe Thiran, Javier Cruz Mota, Julien Meynet

Face detection in images or video sequences is a very challenging problem. It has a wide range of applications but at the same time it presents a great number of difficulties, since faces are non-rigid and very changeable objects that can adopt a lot of di ...

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 ...
