Making Background Subtraction Robust to Sudden Illumination Changes

Pascal Fua, Christoph Strecha, Julien Pilet

Modern background subtraction techniques can handle gradual illumination changes but can easily be confused by rapid ones. We propose a technique that overcomes this limitation by relying on a statistical model, not of the pixel intensities, but of the ill ...

Mammographic texture synthesis: second-generation clustered lumpy backgrounds using a genetic algorithm

François Bochud, Cyril Castella

Synthetic yet realistic images are valuable for many applications in visual sciences and medical imaging. Typically, investigators develop algorithms and adjust their parameters to generate images that are visually similar to real images. In this study, we ...

Real-Time Scalable Motion Planning for Crowds

Daniel Thalmann, Jonathan Maim, Barbara Yersin, Fiorenzo Morini

Real-time crowd motion planning requires fast, realistic methods for path planning as well as obstacle avoidance. The difﬁculty to ﬁnd a satisfying trade-off between efﬁciency and believability is particularly challenging, and prior techniques tend to focu ...

Improving the Fault Tolerance of Nanometric PLA Designs

Giovanni De Micheli, David Atienza Alonso, Luca Benini, Federico Angiolini, Mohamed Haykel Ben Jamaa

Several alternative building blocks have been proposed to replace planar transistors, among which a prominent spot belongs to nanometric laments such as Silicon NanoWires (SiNWs) and Carbon NanoTubes (CNTs). However, chips leveraging these nanoscale struct ...

Internal illumination prediction based on a simplified radiosity algorithm

Darren Robinson

This paper describes a new model for predicting natural interior illumination in the urban context. A simplified radiosity algorithm is used to define the external luminous environment and this model structure is used to predict internal illumination from ...

Real-Time Generation of Annotated Video for Surveillance

Touradj Ebrahimi

We present a system that generates annotated video in realtime. Moving objects are first automatically extracted by means of video analysis and then coded using MPEG4. Moreover, an MPEG7 description of object features is generated. This description is us ...

Towards the Formal Integration of Two Upcoming Standards: IEC61970 and IEC61850

Otto Preiss, Christian Frei, Tatjana Kostic

AbstractThe constant demand for a better integration of utility applications and systems provokes the question on the compatibility of standards that were, and still are, developed for these individual utility disciplines. This paper discusses the need for ...

Bi-directional light transmission properties assessment for venetian blinds : Computer simulations compared to photogoniometer measurements

Marilyne Andersen, Jean-Louis Scartezzini

An accurate evaluation of daylight distribution through advanced fenestration systems (complex glazing, solar shading systems) requires the knowledge of their Bi-directional light Transmission Distribution Function (BTDF). An innovative equipment for the e ...
