In the last decade, traditional dictionary learning methods have been successfully applied to various pattern classification tasks. Although these methods produce sparse representations of signals which are robust against ...

This paper proposes novel exclusive and continuous approaches to guide the search and the retrieval in fingerprint image databases. Both approaches are useful to perform a coarse level classification of fingerprint images ...

Cet article présente un système de reconnaissance du type (constructeur, modèle) de véhicules par vision. À partir d’une vue de face avant d’un véhicule, limitée à sa calandre, nous en construisons une représentation à ...

In some practical classification problems in which the number of instances of a particular class is much lower/higher than the instances of the other classes, one commonly adopted strategy is to train the classifier over ...

Voice signal classification in three types according to their degree of periodicity, a task known as signal typing, is a relevant preprocessing step before computing any perturbation measures. However, it is a time consuming ...

Obstructive sleep apnea-hypopnea syndrome is one of the most common sleep disorders in the general population. It is estimated that this condition affects between 3% and 5% of the adult population worldwide and increases ...

The brain-computer interfaces provide an alternative control of the devices through the activity of the human brain. The selection of channels as a stage for the development of BCI systems allows to evaluate the important ...
