GUI-Aided NIR and Color Image Blending

Sabine Süsstrunk, Radhakrishna Achanta, Andrea Guidi

A near-infrared (NIR) image of a scene contains different information than the corresponding visible spectrum (RGB) image, due to physical phenomena related to scattering, absorption, and reflectance of the different radiation bands. It can be desirable to ...

Automatic and accurate shadow detection from (potentially) a single image using near-infrared information

Sabine Süsstrunk

Shadows, due to their prevalence in natural images, are a long studied phenomenon in digital photography and computer vision. Indeed, their presence can be a hindrance for a number of algorithms; accurate detection (and sometimes subsequent removal) of sha ...

Optimized autofluorescence bronchoscopy using additional backscattered red light

Hubert van den Bergh, Georges Wagnières, Tanja Gabrecht

Autofluorescence bronchoscopy (AFB) has been shown to be a highly sensitive tool for the detection of early endobronchial cancers. When excited with blue-violet light, early neoplasia in the bronchi tend to show a decrease of autofluorescence in the green ...

Method and Apparatus for Generating Digital Halftone Images by Using Multi Color Dithering

Roger Hersch

The invention provides a method and apparatus for the reproduction of color images by multi-color dithering. Multi-color dithering is an extension of bi-level dithering for halftoning an input image using as primary colors an arbitrary number of inks. The ...

Method and system for combining video with spatio-temporal alignment

Martin Vetterli, Paolo Prandoni, Serge Ayer

Given two video sequences (IS1, IS2), a composite video sequence can be generated which includes visual elements from each of the given sequences, suitably synchronized and represented in a chosen focal plane (figure 1). For example, given two video sequen ...

Synthesis of beta -amino-alpha -hydroxy esters and beta -amino-alpha -azido ester by Sharpless asymmetric aminohydroxylation, byproducts analysis

Jieping Zhu

Synthesis of enantiomerically pure beta -amino-alpha -hydroxy esters, e.g., I, and beta -amino-alpha -azido ester using Sharpless AA as a key step is described. A side reaction, the oxidn. of the beta -hydroxy-alpha -amino ester into the alpha ,alpha -di-t ...

Causeway: Support for Controlling and Analyzing the Execution of Web-Accessible Applications

Willy Zwaenepoel

Causeway provides runtime support for the development of distributed meta-applications. These meta-applications control or analyze the behavior of multi-tier distributed applications such as multi-tier web sites or web services. Examples of meta-applicatio ...

Configural and perceptual factors influencing the perception of color transparency

Peggy Gerardin

The mechanisms by which the brain represents colors are largely unknown. In addition, the large number of color phenomena in the natural world has made understanding color rather difficult. Color transparency perception, which is studied in this thesis, is ...

Data coding tools for color-coded vector nanolithography

Andrzej Kulik, Charles Baur, Sébastien Grange, Raphaël Foschia, Saveen Kumar

We propose and demonstrate the ability and efficiency of using a universal file format for a nanolithography pattern. A problem faced by the physicists working in the field of nanolithography is a lack of a flexible pattern design software (possibly open–s ...

Microfabrication of ceramic components by microstereolithography

Philippe Renaud, Arnaud Bertsch, Sébastien Jiguet

Microstereolithography is a technique that allows the manufacture of small and complex three-dimensional (3D) components in plastic material. Many of the components produced by this technique are too small and too complex to be replicated by molding and, c ...
