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.

Abstract: A method and a system are provided to measure transmittance or reflectance of a color specimen by using a transformation matrix obtained from the measurement values of a series of known transmittance or reflectance calibration color standards and multiple flashes from different illumination sources. A color spectrum can be determined with reduced error by calculating the reflectance spectra of an object using measurement matrices obtained under at least two illuminants and the transformation matrix.

Abstract: A system and method are disclosed for correcting the color of microscope images for different illuminants. The system includes a microscope having at least one image setting value selector with a plurality of pre-set positions, and an optical train having a distal end and a proximal end and being configured to convey illumination. The optical train is further configured to allow introduction of a calibration slide into the optical train of the microscope at a plurality of possible positions, each position being a conjugate plane of the sample plane, when the sample is in focus. The calibration slide incorporates an integral transmission filter array of known transmission values.
