Abstract
(EN)
Templates of known forms are stored in computer system. The templates are digitized pixels on which connected component analyses are performed resulting in a first list of components. Five to ten of those components are selected to create an ordered feature list for each form. The computer system then captures an optical image of a form positioned on the top of a stack of forms. The optical image is digitized and stored in the computer (or processor) system as a captured digital image of pixels. A connected component analysis is performed on the captured digital image that results in a second list of image components. Image components on the second list are compared to those on the first list and then each succeeding feature in one of the ordered feature lists. If the comparison is successful, the form is known and other marks on the form may then be processed. If the comparison is unsuccessful, a new feature list is tried.

Des modèles de formulaires connus sont stockés dans un système informatique. Les modèles sont des pixels numérisés sur lesquels des analyses de composant connecté sont effectuées et aboutissent à une première liste de composants. Cinq à dix de ces composants sont sélectionnés pour créer une liste de caractéristiques ordonnées pour chaque formulaire. Le système informatique capture ensuite une image optique d'un formulaire positionné en haut d'une pile de formulaires. L'image optique est numérisée et stockée dans le système informatique (ou processeur) en tant qu'image numérique capturée de pixels. Une analyse de composant connecté est effectuée sur l'image numérique capturée qui aboutit à une seconde liste de composants de l'image. Les composants de l'image de la seconde liste sont comparés à ceux de la première liste et ensuite à chaque caractéristique suivante dans une des listes de caractéristiques ordonnées. Si la comparaison a réussi, le formulaire est connu et d'autres repères sur le formulaire peuvent ensuite être traités. Si la comparaison a échoué, une nouvelle liste de caractéristiques est essayée.
