Abstract
L’invention concerne un procédé de détermination d’un contour de la représentation, sur une photo (2), d’un objet constitué d’un ou plusieurs éléments, dit « contour réel », ledit procédé comportant les étapes suivantes : 1) application d’un premier traitement à la photo de manière à obtenir une première image (10) représentant un premier contour (Co1) dudit objet ; 2) application d’un deuxième traitement à la photo de manière à obtenir une deuxième image (20) représentant un deuxième contour (Co2) dudit objet ; 3) association, suivant un algorithme d’association prédéterminé et pour chaque point (P2) du deuxième contour (Co2), d’un point (P1) du premier contour (Co1) respectif, puis suppression des points du premier contour n’ayant pas été associés à un point du deuxième contour, la première image représentant alors un contour corrigé (Co3) dudit objet Figure d’abrégé : 2
