A method for aligning a modified document and an original document is provided according to an aspect of the present invention. The method includes a step of receiving a first bitmap representative of the modified document, including a first anchor. Additionally, a second bitmap representative of the original document including a second anchor is received. The method also includes the step of deriving a set of first vertex coordinates of the first anchor, and a set of second vertex coordinates of the second anchor. The method further includes the step of transforming the first bitmap to a common reference based upon the first set of vertex coordinates, and the step of transforming the second bitmap to the common reference based upon the second set of vertex coordinates.
L'invention concerne, dans un mode de réalisation, un procédé d'alignement d'un document modifié et d'un document original. Le procédé consiste à recevoir un premier topogramme binaire représentant le document modifié, comprenant un premier élément d'ancrage; à recevoir également un second topogramme binaire représentant le document original, comprenant un second élément d'ancrage; à dériver un ensemble de premières coordonnées de sommet du premier élément d'ancrage et un ensemble de secondes coordonnées de sommet du second élément d'ancrage; à transformer le premier topogramme binaire en une référence commune à partir du premier ensemble de coordonnées de sommet; et à transformer le second topogramme binaire en une référence commune à partir du second ensemble de coordonnées de sommet.
