Abstract

Le procédé selon l'invention permet l'extraction de données brutes d'une image résultant d'une prise de vue. Il comprend la détermination pour chaque point de l'image d'une combinaison V0[C,L] des composantes de la couleur de l'image, le calcul, pour chaque point de l'image, d'une valeur VN+1[C,L], l'itération de ce calcul un nombre prédéterminé de fois puis la prise en compte des valeurs de l'image finale VNfinal [C, L] en chaque point de l'image, le calcul pour chaque point de la différence D [C, L] = VNfinal [C, L] - V0 [C, L], le calcul d'une donnée contextuelle de bruit VS, la correction des données brutes D [C,L] à l'aide de la donnée contextuelle VS, le calcul d'une valeur I* [C, L] corrigée en prenant en compte D* [C, L], et la présentation des données extraites sous un angle souhaité.
