Title (EN) IDENTIFYING DOCUMENT FORMS USING DIGITAL FINGERPRINTS
(FR) IDENTIFICATION DE FORMULAIRES À L'AIDE D'EMPREINTES NUMÉRIQUES
Abstract:
(EN) Techniques are disclosed to identify a form document in an image using a digital fingerprint of the form document. To do so, the image is evaluated to detect features of the image and generate a boundary around each feature. For each boundary, dimensions of the boundary may be stored in a color channel of a pixel in a second image. Thus, the color of the pixel represents the size of the boundary. The second image is the digital fingerprint of the form. To identify the form corresponding to the digital fingerprint, the digital fingerprint may be compared to digital fingerprints of known forms.
(FR) L'invention concerne des techniques d'identification d'un formulaire dans une image à l'aide d'une empreinte numérique du formulaire. À cette fin, l'image est évaluée de façon à détecter des caractéristiques de l'image et à générer une limite autour de chaque caractéristique. Pour chaque limite, les dimensions de la limite peuvent être stockées dans un canal de couleur d'un pixel dans une seconde image. Par conséquent, la couleur du pixel représente la taille de la limite. La seconde image est l'empreinte numérique du formulaire. Pour identifier le formulaire correspondant à l'empreinte numérique, l'empreinte numérique peut être comparée à des empreintes numériques de formulaires connus.
