(FR) ETIQUETTE DE DONNEES ET METHODE DE DETECTION
Abstract
(EN) An identification or data tag composed of a central set of data cells surrounded by border cells which cooperate with their adjacent data cells by constrasting therewith to form a reference perimeter defined by the inter-sections of the boundaries of the border cells with their respective adjoining data cells.
(FR) Une étiquette d'identification ou de données est composée d'une série centrale de cellules de données entourées par des cellules périphériques qui coopèrent avec les cellules de données adjacentes en se distinguant de celles-ci pour former un périmètre de référence définie par les intersections des limites des cellules périphériques avec leurs cellules de données respectives adjacentes.
