Abstract

L'invention concerne un procédé de classification d'une image d'objet appartenant à une catégorie d'objets, ledit procédé comportant une étape préalable d'obtention d'un sous-ensemble (Ej) d'images d'objets de ladite catégorie, ledit sous-ensemble étant associé à un critère de classification, et ledit procédé étant caractérisé en ce qu'il comporte en outre: - une étape de calcul (b1 ) de distance entre ladite image et ledit sous- ensemble (Ej) selon la formule: Dist(q, Ej) = DMC({v1, V2,..., vN}U{q}) - DMC({v1, V2,..., vN}) où : - Dist(q, Ej) est une distance entre un vecteur d'image q correspondant à ladite image et les vecteurs des images dudit sous- ensemble Ej, - (V1, v2,..., vN} sont les vecteurs V1 à vN des images dudit sous- ensemble Ej, - et DMC(x1,...,xp}) est un opérateur qui retourne le déterminant de la matrice de covariance des vecteurs X1 à Xp, assimilés à un nombre P d'observations d'une variable vectorielle aléatoire Xi, i étant un indice variant de 1 à P, - et une étape de comparaison (b2) de la distance ainsi calculée avec un seuil de décision (δj).
