Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Splitting of the recombination zone in organic light emitting diodes by dye doping

Frank Nüesch, Libero Zuppiroli, Detlef Berner, Eduard Tutis, Xiao Wang

In organic light emitting devices, doping of the electroactive organic layer with highly luminescent molecules has been shown to considerably increase device performance and lifetime. In most cases, the doping molecule does not act as a charge donor or an ...

Color image scalable coding with Matching Pursuit

Pascal Frossard, Pierre Vandergheynst

This paper presents a new scalable and highly flexible color image coder based on a Matching Pursuit expansion. The Matching Pursuit algorithm provides an intrinsically progressive stream and the proposed coder allows us to reconstruct color information fr ...

Region-based image classification for automatic color correction

Sabine Süsstrunk

This work presents a framework for image classification based on region information. The main application of this framework is for automatic color correction of real-scene images. Class specific color correction is already implemented in some systems, but ...

Influence of Spectral Sensitivity Functions on color demosaicing

Sabine Süsstrunk, Joanna Marguier

Color images acquired through single chip digital cameras using a color filter array (CFA) contain a mixture of luminance and opponent chromatic information that share their representation in the spatial Fourier spectrum. This mixture could result in alias ...

Reproducing color images with embedded metallic patterns

Roger Hersch, Patrick Emmel

By combining a metallic ink and standard inks, one may create printed images having a dynamic appearance: an image viewed under specular reflection may be considerably different from the same image viewed under non-specular reflection. Patterns which are e ...

Moving object detection between multiple and color images

Touradj Ebrahimi, Emrullah Durucan

There are several publications dedicated to the description and analysis of change detection between two gray-value images. This paper introduces new methods to detect moving objects between multiple images and to detect changes between color images or any ...

Incrustation de microstructures par écarts chromatiques

Electronic imaging devices produce the illusion of synthesizing continuous colors by applying halftones, which are repetitive structures of discrete micro-elements. By themselves, these microstructures do not carry any meaning: their only purpose is to foo ...

Measuring Colourfulness in Natural Images

Sabine Süsstrunk, David Hasler

We want to integrate colourfulness in an image quality evaluation framework. This quality framework is meant to evaluate the perceptual impact of a compression algorithm or an error prone communication channel on the quality of an image. The image might go ...

White-Point Independant RGB Primaries for Color Image Encoding

Sabine Süsstrunk

We present a method to calculate sets of RGB primaries that are white-point independent and have suitable gamut properties when evaluated with regards to surface colors. These primaries can be used as a basis for defining an output-referred color encoding ...
