    Abstract: A method is provided for identifying colors across illuminants using a processor configured by code executing therein, the method comprising capturing a sample image with an image recording device, the image including pixels representing a color sample under analysis and a color reference chart. The processor is also configured to execute comparing the color values of pixels representing the color reference chart of the sample image to the pixel values corresponding to a plurality of entries within a plurality of color reference datasets to determine the dataset representing the closest match of the illumination present at the time the sample image was captured. Using the identified illuminant, the color reference dataset having the closest illuminant is searched for the color under analysis.

    Abstract: An apparatus and method for providing a solution that enables technicians or other technical professionals to obtain accurate gloss, haze and DOI values for a reflecting sample due to the surface conditions of the sample. The apparatus and method allow for the generation of a data model of the surface of a sample using a sensor array designed to detect the divergence of a collimated beam of light reflected off the surface of the sample. The same principle enables technical professionals to obtain accurate haze and clarity values for a transparent or translucent sample that is trans-illuminated by light.

    Abstract: In one or more implementations, the apparatus, systems and methods disclosed herein are directed to configuring a color measurement device to output color measurements that match the expected output of a different color measurement device. In a particular implementation, a method is provided for matching the color measurements made by a color measurement device to the color measurements made by a target color measurement device by implementing a single step color calibration and conversion process using an Artificial Neural Network (ANN). By way of non-limiting example, the raw counts from the color measurement device is converted to a specific color space, such as L*a*b, directly through an ANN. Such ANN is trained to ensure the output of the color measurement from the color measurement device will match with the output of the color measurement from a target color measurement device.

    Abstract: A system including a processor and a memory configured to store code executed by the processor is provided. In one or more implementations, the processor is configured by the code to calibrate measurements made by color measurement devices. In one particular implementation, the processor receives a measurement dataset of one or more color values, for a sample obtained by a color measurement device. The processor is configured to convert the measurement dataset to a standard space measurement dataset using a standard space measurement model and calculate a color dataset based on the standard space measurement dataset using a color conversion model. The processor is further configured to output the calculated color dataset to at least one of a display, database or local memory store.
