Abstract

La présente invention concerne un système de partage d'images permettant de rechercher des images par mot-clé et un procédé s'y rapportant. Un système de partage d'image selon la présente invention est caractérisé par : une partie de communication reliée à un réseau de communication ; une base de données d'images pour le stockage des images ; un module CBIR permettant d'extraire au moins un fichier image ayant une similitude égale ou supérieure à une similitude prédéfinie en comparant un fichier image téléchargé depuis un terminal utilisateur dans le réseau de communication avec les fichiers image stockés dans la base de données d'images ; ainsi qu'une unité de commande permettant de définir un mot-clé pour le fichier image téléchargé en fonction du mot-clé enregistré pour le fichier image extrait par le module CBIR, afin d'enregistrer le fichier image téléchargé et le mot-clé déterminé dans la base de données d'images. Par conséquent, si l'utilisateur saisit un texte dans le système de partage d'images pour rechercher une image, le mot-clé associé à l'image enregistrée est automatiquement donné pour une recherche correcte.
