Abstract

L'invention concerne un système de localisation d'au moins deux points d'intérêt dans une image d'objet. Selon l'invention, un tel système met en œuvre un réseau de neurones artificiels et présente une architecture en couches comprenant: une couche d'entrée (E) recevant ladite image d'objet; au moins une couche intermédiaire (N4), appelée première couche intermédiaire, comprenant une pluralité de neurones (N41) permettant de générer au moins deux cartes de saillance (R5m) associées chacune à un point d'intérêt distinct prédéfini de ladite image d'objet; au moins une couche de sortie (R5) comprenant lesdites cartes de saillance (R5m) lesdites cartes de saillance comprenant une pluralité de neurones connectés chacun à tous les neurones de ladite première couche intermédiaire, lesdits points d'intérêt étant localisés, dans ladite image d'objet, par la position (171, 172, 173, 174) d'un maximum global unique sur chacune desdites cartes de saillance.
