Abstract
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.
