Title
(EN) CUSTOM FUNCTIONAL PATTERNS FOR OPTICAL BARCODES
(FR) MOTIFS FONCTIONNELS PERSONNALISÉS POUR CODES À BARRES OPTIQUES
Abstract
(EN)
Systems and methods for custom functional patterns for optical barcodes are provided. In example embodiments, image data of an image is received from a user device. A candidate shape feature of the image is extracted from the image data. A determination is made that the shape feature satisfies a shape feature rule. In response to the candidate shape feature satisfying the shape feature rule, a custom graphic in the image is identified by comparing the candidate shape feature with a reference shape feature of the custom graphic. In response to identifying the custom graphic, data encoded in a portion of the image is decoded.

L’invention concerne des systèmes et des procédés pour des motifs fonctionnels personnalisés pour codes à barres optiques. Dans des exemples de modes de réalisation, des données d'image d'une image sont reçues d'un dispositif d'utilisateur. Une caractéristique de forme candidate de l'image est extraite des données d'image. Il est déterminé si la caractéristique de forme est conforme à une règle de caractéristique de forme. Si la caractéristique de forme candidate est conforme à la règle de caractéristique de forme, un graphique personnalisé dans l'image est identifié en comparant la caractéristique de forme candidate à une caractéristique de forme de référence du graphique personnalisé. En réponse à l'identification du graphique personnalisé, des données codées dans une partie de l'image sont décodées.
