Correlation between channel state and information source with empirical coordination constraint
Maël Le Treust
Correlation between channel state and source symbol is under investigation for a joint source-channel coding problem. We investigate simultaneously the lossless transmission of information and the empirical coordination of channel inputs with the symbols of source and states. [...]
Study of generalized Radon transforms and applications in Compton scattering tomography
Since the advent of the first ionizing radiation imaging devices initiated by Godfrey Newbold Hounsfield and Allan MacLeod Cormack, Nobel Prizes in 1979, the requirement for new non-invasive imaging techniques has grown. These techniques rely upon the properties of penetration in the matter of X and gamma radiation for detecting a hidden structure without destroying the illuminated environment. [...]
Traitement de requêtes top-k multicritères et application à la recherche par le contenu dans les bases de données multimédia
Efficient processing of ranking queries is an important issue in today information retrieval applications such as meta-search engines on the web, information retrieval in social networks, similarity search in multimedia databases, etc. We address the problem of top-k multi-criteria query processing, where queries are composed of a set of ranking predicates, each one expressing a measure of similarity between data objects on some specific criteria.
