Abstract:
A method, non-transitory computer readable medium, and apparatus for calibrating a device using augmented data are disclosed. For example, the method measures k spectral values of each patch for a first plurality of patches generated by the device and a second plurality of patches generated by the reference device, creates a first augmented data set by selecting a delta (δ), wherein the first augmented data set comprises the δ applied k times to each one of the k spectral values of each one of the first plurality of patches, initializes initializing a function to create a second augmented data set for the reference device, solves the function to obtain a matrix of calibration values of the device that is based upon the first augmented data set and the second augmented data set and calibrates the device using the matrix of calibration values.
