GRASP Special Seminar – Roberto Tron, Johns Hopkins University, “Consensus Algorithms on Manifolds and Localization of Camera Networks”

April 2, 2012 @ 1:30 pm - 2:30 pm

Abstract: Consensus algorithms are a popular choice for computing averages and
other aggregate functions in ad-hoc wireless sensor networks. However,
existing work mostly addresses the case where the measurements lie in a
Euclidean space. In the first part of the talk we will present
Riemannian consensus, a natural extension of consensus algorithms to
Riemannian manifolds. We will discuss its convergence properties and
their dependence on various factors, such as choice of the distance
function, network connectivity, geometric configuration of the
measurements and curvature of the manifold. In the second part of the
talk we will focus on the problem of distributed 3-D camera network
localization, and show how ideas and analysis techniques from
Riemannian consensus can be extended and applied to this problem.

honors) in 2007 in Telecommunication Engineering from the Politecnico
di Torino in Italy. He also received a Diplome d’Engenieur from the
Eurecom Institute and a DEA degree from the Universit’e de Nice
Sophia-Antipolis in 2006. He is currently a PhD student in the
Department of Electrical and Computer Engineering at the Johns Hopkins
University. He received the “General chair’s Interactive Presentation
Recognition Award” and the “Best Student Paper Runner-up Award” from
the IEEE Conference on Decision and Control in 2009 and 2011,
respectively. His research interests include motion segmentation and
distributed algorithms on camera sensor networks.
