Claim:
1. A method for calibrating a device to a reference device using augmented data, comprising measuring, by a processor, 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, wherein k is a number of spectral values; creating, by the processor, a first augmented data set for the device by selecting a delta (δ), wherein the delta comprises a value derived from a cost function, 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; initializing, by the processor, a function to create a second augmented data set for the reference device, wherein the second augmented data set comprises the δ times a gain applied k times to each one of the k spectral values of each one of the second plurality of patches and a matrix of calibration values that is based upon the first augmented data set and the second augmented data set; solving, by the processor, the function to obtain the matrix of calibration values for the device that is based upon the first augmented data set and the second augmented data set; and calibrating, by the processor, the device using the matrix of calibration values.
