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.

VLSI implementation of MIMO detection using the sphere decoding algorithm

Andreas Peter Burg, Matthieu Philippe Emmanuel Zellweger

Multiple-input multiple-output (MIMO) techniques are a key enabling technology for high-rate wireless communications. This paper discusses two ASIC implementations of MIMO sphere decoders. The first ASIC attains maximum-likelihood performance with an avera ...

Fast Index Assignment for balanced N-Description Scalar Quantization

Pascal Frossard, Ivana Radulovic

In this paper, we address the design of any number of balanced descriptions using multiple description scalar quantization (MDSQ), based on fast index assignment. The proposed scheme has the advantages of low complexity, and the possibility of being extend ...

Solving the fixed rank convex quadratic maximization in binary variables by a parallel zonotope construction algorithm

Thomas Liebling, Jean-Albert Ferrez

We address the weighted max-cut problem, or equivalently the problem of maximizing a quadratic form in n binary variables. If the underlying (symmetric) matrix is positive semidefinite of fixed rank d, then the problem can be reduced to searching the extre ...

A No-Reference Perceptual Blur Metric

Touradj Ebrahimi, Pina Marziliano, Frédéric Dufaux, Stefan Winkler

In this paper, we present a no-reference blur metric for images and video. The blur metric is based on the analysis of the spread of the edges in an image. Its perceptual significance is validated through subjective experiments. The novel metric is near re ...

Distance transformations: fast algorithms and applications to medical image processing

Olivier Cuisenaire

Medical image processing is a demanding domain, both in terms of CPU and memory requirements. The volume of data to be processed is often large (a typical MRI dataset requires 10 MBytes) and many processing tools are only useful to the physician if they ar ...

Finding all common bases in two matroids

In this paper, we present an algorithm for finding all common bases in two matroids. Our algorithm lists all common bases by using pivot operations in such a way that each basis appears exactly once. The time complexity of the algorithm is O(n(n^2+t)§) whe ...

1995

This paper addresses seven questions with respect to the transfer, integration, amplification and genetic stability of recombinant DNA in mammalian genomes. Most of these questions were raised with those issues in mind which are frequently discussed in the ...
