Dense Depth Estimation from Omnidirectional Images

Pascal Frossard, Zafer Arican

This paper addresses the problem of dense disparity estimation in networks of omnidirectional cameras. We propose to map omnidirectional images on the 2-sphere, and we perform disparity estimation directly on the sphere in order to preserve the geometry of ...

Automatic nonverbal analysis of social interaction in small groups: A review

Daniel Gatica-Perez

An increasing awareness of the scientific and technological value of the automatic understanding of faceto- face social interaction has motivated in the past few years a surge of interest in the devising of computational techniques for conversational analy ...

Real-time input-constrained MPC using fast gradient methods

Colin Neil Jones

Linear quadratic model predictive control (MPC) with input constraints leads to an optimization problem that has to be solved at every instant in time. Although there exists computational complexity analysis for current online optimization methods dedicate ...

Performance Evaluation of a Multi-band UWB Location and Communication System Based on Modified Gegenbauer Functions

Ultra wide band (UWB) may offer very efficient solutions for various communication and sensing applications. Two approaches have emerged, which meet all the communication requirements: impulse and multi-band systems. The present work is concerned in the se ...

Image Reconstruction in the Gigavision Camera

Martin Vetterli, Edoardo Charbon, Sabine Süsstrunk, Luciano Sbaiz, Feng Yang

Recently we have proposed a new image device called the gigavision camera. The main feature of this camera is that the pixels have a binary response. The response function of a gigavision sensor is non-linear and similar to a logarithmic function, which ma ...

Impact de la communication voco-visuelle dans le management sur la motivation des collaborateurs

Our research work wishes to highlight the importance of the relationship between the vocal and physical behaviour of the manager and team motivation. In order to investigate this important relationship, a survey by means of a questionnaire and two field st ...

Chasing the Weakest System Model for Implementing Omega and Consensus

Martin Hutle

Aguilera et al. and Malkhi et al. presented two system models, which are weaker than all previously proposed models where the eventual leader election oracle Omega can be implemented, and thus, consensus can also be solved. The former model assumes unicast ...

On the Specification of Partitionable Group Membership

André Schiper, Stefan Pleisch, Olivier Rütti

Group communication in partitionable systems has been the focus of many research activities over the last decade. Fault-tolerant applications in a partitionable system model generally rely on two basic services: a group membership service and a reliable mu ...

A formal approach to fault tolerant distributed consensus

Rachele Fuzzati

The term distributed Consensus denotes the problem of getting a certain number of processes, that could be far away from each other and that exchange messages through some communication means, to all agree on the same value. This problem has been proved im ...

Multiple Heterogeneous Ant Colonies with Information Exchange

Arash Arami, Bijan Rahimzadeh Rofoee

The method of multiple heterogeneous ant colonies with information exchange (MHACIE) is presented in this paper with emphasis on the speed of finding the optimal solution and the corresponding computational complexity. The proposed method which is inspired ...
