Progressive quantization in distributed average consensus
Dorina Thanou, Effrosyni Kokiopoulou, Pascal Frossard
We consider the problem of distributed average consensus in a sensor network where sensors exchange quantized information with their neighbors. We propose a novel quantization sche…
3D Face Recognition with Sparse Spherical Representations
R. Sala Llonch, E. Kokiopoulou, I. Tosic +1
This paper addresses the problem of 3D face recognition using simultaneous sparse approximations on the sphere. The 3D face point clouds are first aligned with a novel and fully au…
Graph-based classification of multiple observation sets
Effrosyni Kokiopoulou, Pascal Frossard
We consider the problem of classification of an object given multiple observations that possibly include different transformations. The possible transformations of the object gener…
Polynomial Filtering for Fast Convergence in Distributed Consensus
Effrosyni Kokiopoulou, Pascal Frossard
In the past few years, the problem of distributed consensus has received a lot of attention, particularly in the framework of ad hoc sensor networks. Most methods proposed in the l…
