A Web Survey for Facial Expressions Evaluation

Michel Bierlaire, Jean-Philippe Thiran, Matteo Sorci, Gianluca Antonini

In the recent years, researchers have investigated several methods of facial expression analysis. Their interest has been to apply their algorithms to sets of images labelled by a restrained number of experts. In order to deal with the generalizability of ...

Broadcast and Slepian-Wolf multicast over Aref Networks

Satish Babu Korada, Dinkar Vasudevan

We consider source coding over Aref networks. In particular we consider the following two problems: (i) multicasting correlated sources to a set of receivers, (ii) broadcasting sources to their respective receivers. For the first problem we show necessary ...

Compute-and-Forward: Harnessing Interference with Structured Codes

Michael Christoph Gastpar

For a centralized encoder and decoder, a channel matrix is simply a set of linear equations that can be transformed into parallel channels. We develop a similar approach to multiuser networks: we view interference as creating linear equations of codewords ...

Illuminant retrieval for fixed location cameras

Sabine Süsstrunk, Joanna Marguier

Fixed location cameras, such as panoramic cameras or surveillance cameras, are very common. In images taken with these cameras, there will be changes in lighting and dynamic image content, but there will also be constant objects in the background. We propo ...

Atoms of all channels, unite! Average case analysis of multi-channel sparse recovery using greedy algorithms

Pierre Vandergheynst, Rémi Gribonval, Karin Schnass

This paper provides new results on computing simultaneous sparse approximations of multichannel signals over redundant dictionaries using two greedy algorithms. The first one, p-thresholding, selects the S atoms that have the largest

Waypoint navigation with a MAV

Adrien Briod

The goal of the project is to implement a waypoint navigation using GPS as the position input, for an outdoor MAV. A waypoint navigation allows an operator to set a number of places (waypoints) where he wants the plane to pass. The waypoint navigation impl ...

Efficient Protocols for Set Membership and Range Proofs

Rafik Chaabouni

We consider the following problem: Given a commitment to a value σ, prove in zero-knowledge that σ belongs to some discrete set Φ. The set Φ can perhaps be a list of cities or clubs; often Φ can be a numerical range such as [1, 220]. This problem arises in ...

Aligator: A mathematica package for invariant generation

Laura Ildiko Kovacs

We describe the new software package Aligator for automatically inferring polynomial loop invariants, The package combines algorithms from symbolic summation and polynomial algebra with computational logic, and is applicable to the rich class of P-solvable ...

A geometric framework for solving subsequence problems in computational biology efficiently

Friedrich Eisenbrand

In this paper, we introduce the notion of a constrained Minkowski sumwhich for two (finite) point-sets P,Q R2 and a set of k inequalities Ax b is defined as the point-set (P Q)Ax b= x = p+q | P, q Q, Ax b. We show that typical subsequ ...

A multiresolution approach to automated classification of protein subcellular location images

Yann Barbotin, Amina Chebira

Fluorescence microscopy is widely used to determine the subcellular location of proteins. Efforts to determine location on a proteome-wide basis create a need for automated methods to analyze the resulting images. Over the past ten years, the feasibility o ...
