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.
In this paper we propose a novel method which is able to detect and separate audio-visual sources present in a scene. Our method exploits the correlation between the video signal captured with a camera and a synchronously recorded one-microphone audio trac ...
This thesis describes innovative techniques for reducing speckle noise and improving the intensity profile of the speckle correlation fringes. The methods are based on reducing the range of the modulation intensity values of the speckle interference patter ...
In wireless portable applications, a large part of the signal processing is performed in the digital domain. Digital circuits show many advantages. The power consumption and fabrication costs are low even for high levels of complexity. A well established a ...
The transceivers of a wireless sensor network (WSN) have to fulfill the low-power and low-voltage constraints. The WiseNET project has already proven that it is possible to design a receiver working at 1V and consuming less than 2mW. However this transceiv ...
In this paper we present current mode, programmable, binary tree MIN/MAX filters designed for nonlinear data processing. Proposed circuits can be used in image filtration, to realize operations such as erosion or dilatation that are useful in noise reducti ...
In this paper, a novel circuit referred to as complex Gm-C sampler that can be used for sub-sampling IF signals is presented. The circuit employs a conventional cross-coupled Gm-C filter structure with a built-in sampler to combine th ...

In the following study is presented two research works: the first is concerned with the elaboration of an intelligent meeting room while the second is about the development of a real time high definition video server capable of advanced accessibility optio ...
The aim of the present study was to monitor photodynamic angioocclusion with verteporfin in capillaries. Details of this process were recorded under a microscope in real-time using a high-sensitivity video camera. A procedure was developed based on intrave ...
A new odd-order frequency multiplier topology is demonstrated in this work that uses a subharmonic mixer to realize a frequency tripler. A feedforward circuit is used for fundamental cancellation at the output and eliminates the need for filtering structur ...

A novel idea and CMOS implementation of power-efficient 1-D and 2-D finite-impulse-response (FIR) filters based on a current-mode Gilbertvector- multiplier (GVM) have been proposed. MOS transistors included in the GVM multiplier work in a weak inversion re ...
