Optimisation conjointe de méthodes de linéarisation de l'émetteur pour des modulations multi-porteuses
Multi-carrier modulations appear as a well-tried technology for high-speed data transmission on potentially disrupted channels. OFDM (Orthogonal Frequency Division Multiplexing) has been chosen for that matter in several telecommunication standards (ADSL, Wi-Max, IEEE 802. [...]
Semi-automatic Classification of Remote Sensing Images
Jefersson Alex Dos Santos
A huge effort has been made in the development of image classification systemswith the objective of creating high-quality thematic maps and to establishprecise inventories about land cover use. The peculiarities of Remote SensingImages (RSIs) combined with the traditional image classification challengesmake RSI classification a hard task. [...]
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.
