Automatic and Accurate Shadow Detection using Near-Infrared Information
Sabine Süsstrunk, Dominic Rüfenacht
We present a method to automatically detect shadows in a fast and accurate manner by employing the inherent sensitivity of digital camera sensors to the near-infrared (NIR) part of the spectrum. Shadows are generally found in the dark parts of an image, be ...
2012Perceptual 3D rendering based on principles of analytical cubism
Cubism, pioneered by Pablo Picasso and Georges Braque, was a breakthrough in art, influencing artists to abandon existing traditions. In this paper, we present a novel approach for cubist rendering of 3D synthetic environments. Rather than merely imitating ...
2012Temporal Synchronization in Stereoscopic Video: Influence on Quality of Experience and Automatic Asynchrony Detection
Touradj Ebrahimi, Jong Seok Lee, Lutz Goldmann
In this paper, we analyze the influence of temporal asyn- chrony on the subjective quality of stereoscopic video. Based on our recently created 3D video database, different levels of asynchrony were simulated and a comprehensive subjective test was conducte ...

In situ rates of reductive dissolution in submerged shoreline sediments at Lake Tegel (Berlin, Germany) were measured with a novel hydrous manganese (Mn) oxide-doped gel probe sampler in concert with equilibrium gel probe and sequential extraction measurem ...
2010Stencil mask for accurate pattern replication
The stencil mask diminishes thermal effects on alignment between stencil and substrate, and reduces the overall presence of a gap between stencil and substrate. In addition, this design allows for easy interchange of stencils, making local alterations of s ...
2007EVAPORATION THROUGH SHADOW MASKS ON UNCONVENTIONAL SUBSTRATES
Jürgen Brugger, Marc Antonius Friedrich van den Boogaart, Chantal Imboden
While standard photolithography methods have proven themselves in semiconductor applications, they have fundamental limitations when considered for the fabrication of advanced micro/nanosystems (MEMS/NEMS). MEMS and NEMS often use “soft” materials such as ...
2005Efficient raytracing of deforming point-sampled surfaces
We present efficient data structures and caching schemes to accelerate ray-surface intersections for deforming point-sampled surfaces. By exploiting spatial and temporal coherence of the deformation during the animation, we are able to improve rendering pe ...
2005Electrical and mechanical activity of the intestine
The intestine is today still an organ whose mechanisms of functions are not fully understood. The diffculty in its understanding comes from the fact that it is regulated by a complex network of signals of different natures. Granting that a multitude of exp ...
EPFL2005Perspective accurate splatting
We present a novel algorithm for accurate, high quality point rendering, which is based on the formulation of splatting using homogeneous coordinates. In contrast to previous methods, this leads to perspective correct splat shapes, avoiding artifacts such ...
2004Shadow identification and classification using invariant color models
Touradj Ebrahimi, Elena Salvador
A novel approach to shadow detection is presented in this paper. The method is based on the use of invariant color models to identify and to classify shadows in digital images. The procedure is divided into two levels: first, shadow candidate regions are e ...
