Linear Gaussian State-Space Models are widely used and a Bayesian treatment of parameters is therefore of considerable interest. The approximate Variational Bayesian method applied to these models is an attractive approach, used successfully in application ...
We present a methodology for modeling heterogeneous real-time components. Components are obtained as the superposition of three layers: behavior, specified as a set of transitions; Interactions between transitions of the behavior; Priorities, used to choos ...
The article describes the philosophy of component approach to system design, illustrated on the optical transmission network example. The approach is based on the object oriented paradigms of Cosmos and Nyx tools. Cosmos serves as the support for system an ...
This report presents a new method to confront the Blind Audio Source Separation (BASS) problem, by means of audio and visual information. In a given mixture, we are able to locate the video sources first and, posteriorly, recover each source signal, only w ...
This paper proposes an application of information theoretic approach for finding the most informative subset of eigenfeatures to be used for audio-visual speech recognition tasks. The state-of-the-art visual feature extraction methods in the area of speech ...
This paper presents a method for multiple description coding, by clustering generic redundant dictionaries into blocks of N atoms. Since these blocks are likely to gather coherent atoms, the encoder can distribute atoms from the same coherent block to diff ...
In this paper, we present a novel high resolution optical imaging device on chip. It is based on a line of nano holes defined in an optically opaque aluminum film on a CMOS imaging sensor chip. Because it's free of bulky optical elements and compatible to ...
We propose a new method to render high dynamic range images that models global and local adaptation of the human visual system. Our method is based on the center-surround Retinex model. The novelties of our method is first to use an adaptive surround, whos ...

Package universes is a component-distribution architecture based on explicitly managing the set of components visible at assembly time. The architecture is usable as is for a number of common organizations and software-engineering processes. Also, by provi ...
Contextual information is important for sequence modeling. Hidden Markov Models (HMMs) and extensions, which have been widely used for sequence modeling, make simplifying, often unrealistic assumptions on the conditional independence of observations given ...
