Title (EN) PROVIDING A DIGITAL COPY OF A SOURCE IMAGE
(FR) FOURNIR UNE COPIE NUMÉRIQUE D’UNE IMAGE SOURCE
Abstract:
(EN) The present invention relates to a method for an automatic alignment of digital image layers, implemented in specific software on a computing device (e.g. a personal computer (1 )) which drives an image scanner (3) and aligns the multiple scanned image layers (25) in such a way, that of these layers (25) one resulting image (10) will be created, which has - by a statistical calculus based on multiple sampling and averaging of these multiple scanned image layers (25) - a decreased random distributed noise spectrum compared to single scanned images (25) and by the automatic alignment avoids a decrease in sharpness using statistical comparison of the multiple layers (25), especially deviation and cost functions, aiming to compensate a misalignment (6), e.g. mechanical mismatches of the scanner's (3) scanning carriage, between multiple scans (25).
(FR) La présente invention concerne une méthode d’alignement automatique de couches d’image numérique, implémentée dans un logiciel spécifique d’un dispositif de calcul (par exemple un ordinateur personnel (1)), qui pilote un scanneur d’image (3) et aligne les multiples couches d’image numérisées (25), de manière telle qu’à partir de ces couches (25) soit créée une image résultante (10), qui - par un calcul statistique basé sur l’échantillonnage multiple et le moyennage de ces multiples couches d’image numérisées (25) - possède un spectre de bruit à distribution aléatoire, comparée à des images à numérisation unique (25) et qui, grâce à l’alignement automatique, évite une diminution du piqué par l’emploi d’une comparaison statistique des multiples couches (25), spécialement de fonctions d’écart et de coût, qui tente de compenser un désalignement (6), par exemple du fait de non-concordances mécaniques du chariot de balayage du scanneur (3) lors de numérisations multiples (25).
