[Homelab] [Projects] [People] [Publications]

Various applications librairies for algorithms of signal processing (filtering, fast transforms, parametric models, neural networks, ...) are available and optimized for software implementations (PDAs, microprocessors and microcontrollers [RISC, DSP]) or hardware implementations (CPLD, FPGA). The languages we use are assembly languages, C/C++, JAVA and VHDL.

Applications : digital filtering, speech processing, image processing, data transmissions (modems),.. .


Current R&D projects

The DiYSE project (2009 - 2011)

The Do-it-Yourself Smart Experiences project (DiYSE) aims at enabling ordinary people to easily create, setup and control applications in their smart living environments as well as in the public Internet-of-Things space, allowing them to leverage aware services and smart objects for obtaining highly personalised, social, interactive, flowing experiences at home and in the city.

The MediaTIC project (2008 - 2015)

The MediaTIC portfolio was submitted in September 2007 in response to the first call for proposals of the ERDF and started on 1st July, 2008. This ambitious project falls within the scope of measure 2.2 dedicated to the exploitation of the potential of research centres. More concretely, the project's objective is to increase the competitiveness of innovating technological SMEs in Wallonia through collective projects dictated by concrete industrial requests. It works as a cross-action for the innovation in the NTIC component of each strategic line defined by the Walloon Marshall Plan.
To reach that goal, Multitel, as a project leader, has gathered a consortium composed of academic entities and research centres split all over the Walloon territory. Actually, MediaTIC has been submitted in both objectives of the period for 2007-2013 of the European structural funds programme, namely "Convergence" and "Regional Competitiveness and employment". The project counts on the know-how of laboratories such as the SEMI, TCTS and Telecommunications units of the Faculté polytechnique de Mons, the TELE laboratory from the Catholic University of Louvain-la-Neuve, of the research units in microelectronics (Microsys) and signal & image processing (Intelsig) from the University of Liege, of the Centexbel and SIRRIS research centres and finally, of the GIE MUWAC. By calling upon complementary partners, Multitel aimed at providing MediaTIC with the typical action leverages of a collaborative research and allowing the projects focusing towards common objectives.
MediaTIC is a portfolio of six integrated projects oriented towards specific industrial needs. Each one is run by a specialist from Multitel in the targeted field. These thematic platforms are Transmedia, Envimedia, Tracemedia, Intermedia, 3Dmedia and Optimedia.

The NUMEDIART project (2007 - 2012)

Numediart is a long-term research programme centered on Digital Media Arts, funded by Région Wallonne, Belgium (grant N°716631). Its main goal is to foster the development of new media technologies through digital performances and installations, in connection with local companies and artists.
It is organized around three major R&D themes: HyFORGE - hypermedia navigation, COMEDIA - body and media, COPI - digital instrument making. It is performed as a series of short (3-months) projects, typically 3 or 4 of them in parallel, which are concluded by a 1-week "hands on" workshop.
Numediart is the result of collaboration between Polytech.Mons (Information Technology R&D Department) and UCL (TELE Lab), with a center of gravity in Mons, the cultural capital of Wallonia. It also benefits from the expertise of the Multitel research center on multimedia and telecommunications. As such, it is the R&D component of MONS2015, a broader effort towards making Mons the cultural capital of Europe in 2015.

The TRANSLOGISTIC project (2007 - 2011)

TransLogisTIC is an ambitious research project financed by the Walloon Region (2.5 years - 14 m. euros) which is built around a longterm strategy aimed at developing a complete and efficient multimodal transport system in Wallonia as well as high quality logistics services with high added value. Supported by internationnaly recognized Walloon actors (10 enterprises and 5 universities), the project will result in the creation of innovative and efficient products and services.

The F3M project (2004 - 2008)

The goal of the project is to assess the usability of a solution based on wearable computer connected through a wireless network for improvement of the workflow in the field of maintenance, for instance for planes in the aviation sector and for trains in the railways sector. Our concept will equip any field technician with a mobile wearable computer allowing communication in real time with its colleagues and with a central server supervising all the field maintenance process and connected with the existing maintenance database used more traditionally.

The LASEF project (2004 - 2008)

Le but de ce projet est la démonstration d'un système LIDAR (LIght Detection And Ranging) pour la détection des turbulences et flux d'air et en établir un modèle théorique. Le système sera basé sur la détection des mouvements de particules dans l'air par effet Doppler. Cette technique met en jeu une source d'émission LASER couplée à un appareil de détection de la lumière rétro-diffusée par les particules. L'aboutissement du projet consistera en la démonstration d'une mesure de détection de type LIDAR, à l'aide d'un appareil fiable et transportable sur terrain. En effet, la fréquence des atterrissages et des décollages dans les aéroports est telle qu'il est primordial de vérifier que la distance entre avions est suffisante, notamment dans le sillage des grands porteurs (A380 notamment). L'application directe recherchée est donc une mesure des turbulences à l'atterrissage ou au décollage d'un avion.

Past R&D projects

The SYPOLE project (2003 - 2006)

The blind or partially sighted people represent 17.5 million people in Europe and about 75.000 in Wallonia. For most of these people, much information, which exists in written or imaged forms, is not easily accessible for them. The main aim of Sypole project is to remedy all these needs by the realization of a prototype device, which will be portable, autonomous, small-size and easy to use for blind or partially sighted people. This kind of device will be able to recognize text and coloured forms, such as logos, and to auto-generate a speech signal.

The MODIVOC project (2002 - 2004)

Speech-based interfaces are about be used in many applications, for which the most demanding is that of being able to recognize any person (without prior training of the machine), even in noisy conditions. The techniques required to achieve this are mostly availble, but their use in real portable applications is limited by their memory and CPU comsuption. MODIVOC aims at :

  • simplifying ASR algorithms
  • increasing their robustness
  • dispatching CPU load among portable computers in a network
  • specifying generic models to apply this solution in heteogeneous environements

DIALOGUE (2000 - 2004) - PhD Thesis Olivier Pietquin

This book addresses the problems of spoken dialogue system design and especially automatic learning of optimal strategies for man-machine dialogues. Besides the description of the learning methods, this text proposes a framework for realistic simulation of human-machine dialogues based on probabilistic techniques, which allows automatic evaluation and unsupervised learning of dialogue strategies. This framework relies on stochastic modelling of modules composing spoken dialogue systems as well as on user modelling. Special care has been taken to build models that can either be hand-tuned or learned from generic data.
