Title
(EN) INTER-INSTRUMENT VARIATION CORRECTION
(FR) CORRECTION DE VARIATION ENTRE INSTRUMENTS
Abstract
(EN)
Embodiments of the present invention are directed towards systems, methods and computer program products for correcting inter-instrumentation variation among color measurement devices. In one particular implementation, a method for correcting inter-instrument variation among color measurement devices includes obtaining a set of color measurements of an item under analysis. The described approach also includes accessing a conversion model, wherein the conversion module has been generated using one or more ANN back propagated over a collection of data points, where the data points correspond to measurements of a color standard using devices from a control device batch and a test device batch. Using the conversion module, a processor is configured to transform the set of color measurements into a calibrated color measurement set. The calibrated color measurement set is then output to at least one display, memory or remote computing device.

Selon certains modes de réalisation, cette invention concerne des systèmes, des procédés et des produits de programme informatique pour corriger la variation entre instruments parmi des dispositifs de mesure de couleur. Selon un mode de réalisation particulier, un procédé de correction de la variation entre instruments parmi des dispositifs de mesure de couleur consiste à obtenir un ensemble de mesures de couleur d'un article en cours d'analyse. L'approche décrite comprend également l'étape consistant à accéder à un modèle de conversion, le modèle de conversion ayant été généré à l'aide d'un ou de plusieurs réseaux neuronaux artificiels propagés en retour sur une collection de points de données, les points de données correspondant à des mesures d'une norme de couleur à l'aide de dispositifs provenant d'un lot de dispositifs de contrôle et d'un lot de dispositifs de test. A l'aide du module de conversion, un processeur est configuré pour transformer l'ensemble de mesures de couleur en un ensemble étalonné de mesures de couleur. L'ensemble étalonné de mesures de couleur est ensuite fourni en sortie à au moins un dispositif d'affichage, de mémoire ou de calcul à distance.
