Extension of the Global Matched Filter to structured groups of atoms: Application to harmonic signals
When seeking a sparse representation of a signal on a redundant basis, one might want to convey available a priori information on the observations to the optimization criterion. I...

Approximation of pattern transformation manifolds with parametric dictionaries
The construction of low-dimensional models explaining highdimensional signal observations provides concise and efficient data representations. In this paper, we focus on pattern ...

Wavelet domain detection of rust in steel bridge images
This paper describes the detection of rust defects on highway steel bridges, which are one of the most commonly observed defects on coating surfaces and thus have to be taken care...

Prediction and Fault Detection of Environmental Signals with Uncharacterised Faults
Many signals of interest are corrupted by faults of an unknown type. We propose an approach that uses Gaussian processes and a general “fault bucket” to capture a priori uncha...

Brief Announcement: The Minimum Failure Detector for Non-Local Tasks in Message-Passing Systems
This paper defines the basic notions of local and non-local tasks, and determines the minimum information about failures that is necessary to solve any non-local task in message-p...
