Abstract: A processing system of a mobile device acquires an image of an object of a target color, wherein the image was captured by an integrated digital camera of the mobile device, calculates a first plurality of values that describes the target color, and wherein the calculating is based on an analysis of a pixel of the image, and identifies a first candidate color from among a plurality of candidate colors, wherein each candidate color in the plurality of candidate colors is associated with a second set of values that describes the each candidate color, and wherein the second set of values describing the first candidate color matches the first set of values more closely than any second set of values associated with another candidate color of the plurality of candidate colors.

Abstract: A system and apparatus for the color calibration of images recorded through a microscope. An integrated color calibration target microscope slide device and specimen are recorded with an imaging device that acquires both the color values of the specimen and the color values of the color calibration target under a plurality of illuminations and trans-illuminations. A composite image is formed to provide a spectral estimation of the relevant color values of the image. The image is converted into multi-stimulus values governed by a plurality of illuminating conditions. The multi-stimulus values are used to provide image calibration data so that color values of the image, when displayed on a display devices, are faithfully reproduced.

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.
