Abstract

L'invention se rapporte à des systèmes et à des procédés d'analyse d'une image source. Un ensemble de données d'image source est généré à partir de l'image source. Cet ensemble de données d'image source comprend des données d'affichage et des données d'emplacement. Ces données d'emplacement indiquent l'emplacement des données d'affichage comportant une référence au système coordonné bidimensionnel. Les données d'affichage sont utilisées afin de reproduire l'image source. Un modèle de surface est généré en fonction de l'ensemble de données d'image source. Ce modèle de surface est défini par des données d'emplacement correspondant aux données d'emplacement de l'ensemble de données d'image source et par des données d'intensité générées en fonction des données d'affichage. Le modèle de surface est interrogé afin de déterminer les caractéristiques de l'image source.
