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.

Saliency-driven Black Point Compensation

Sabine Süsstrunk, Albrecht Johannes Lindner

We present a novel framework for automatically determining whether or not to apply black point compensation (BPC) in image reproduction. Visually salient objects have a larger influence on determining image quality than the number of dark pixels in an imag ...

Using the Wiimote as a sensor in water research

Steven Vincent Weijs

The $40 “Wiimote” (an input device belonging with the Nintendo® Wii™ game system) can be used by hydrologists as a sensor. The device contains three accelerometers and an infrared camera with built-in source tracking. It communicates by Bluetooth®. Because ...

Calibrating the ink spreading curves enhanced Yule-Nielsen modified spectral Neugebauer model with the two-by-two dot centering printer model

Roger Hersch, Romain Rossier

The Yule-Nielsen modified spectral Neugebauer model enhanced for accounting for ink spreading in the different ink superposition conditions (EYNSN) requires measuring the reflectances of halftone calibration patches in order to compute the ink spreading cu ...

Mental vision

Achille Peternier

Despite the wide amount of computer graphics frameworks and solutions available for virtual reality, it is still difficult to find a perfect one fitting at the same time the many constraints of research and educational contexts. Advanced functionalities an ...

Spectral prediction model for variable dot-size printers

Roger Hersch, Thomas Bugnon

By printing a variable number of droplets onto the same pixel location, ink jet printers produce pixels at variable dot-sizes yielding several darkness levels. Varying the number of printed droplets affects the ink volume deposited onto the substrate. In t ...

An Experimental Platform for an Indoor Location and Tracking System

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain

In this paper, an experimental platform for indoor location and tracking using ultra wideband (UWB) impulse radio signals is presented and its performance measured. The platform has been developed entirely using standard electronic components that are comm ...

Microcamera Embedded in a Wristwatch

Pierre-André Farine, Steve Tanner, Michael Ansorge, Patrick Stadelmann

The presentation reports upon the conception and realization of a miniature very low-power microcamera system that has been embedded in a wristwatch so as to enable the spontaneous capture of photographs in everyday life based on timekeeping devices the us ...

Rendering massive real-time crowds

Pablo Stanislaw De Heras Ciechomski

This thesis presents how to visualize a large crowd of virtual human characters in real time on a standard issue personal computer. The virtual humans are distributed into rendering fidelities such that the humans closer to the viewer are detailed and expr ...

Prediction model for color separation, calibration and control of printers

Roger Hersch, Patrick Emmel

The present invention facilitates the calibration of printers and the color separation of input images into a set of inks by disclosing methods and systems for populating device-calibration lookup tables. The disclosed methods and systems rely on a compreh ...

Evolutionary Bits'n'Spikes

Dario Floreano, Gilles Caprari, Jesper Blynel

We describe a model and implementation of evolutionary spiking neurons for embedded microcontrollers with few bytes of memory and very low power consumption. The approach is tested with an autonomous microrobot of less than 1 in^3 that evolves the ability ...
