Patent ID: 8390906

Claim:
A method of characterizing a color reproduction device, the method comprising: providing a forward color transform for the device mapping color from a first color space associated with an internal color representation of the device to a second color space representing measurements of observed color values, the forward color transform including a parametric surface forward color transform and a nonparametric residual forward color transform; producing a plurality of visible adaptation test images according to an input adaptation data set in the first color space using the device; measuring the adaptation test images to generate a measured adaptation data set in the second color space; and using at least one processor, adapting the parametric surface forward color transform using the input adaptation data set and the measured adaptation data set; using the at least one processor, generating a prediction data set in the second color space using the adapted parametric surface forward color transform and the nonparametric residual forward color transform; using the at least one processor, generating a prediction error data set in the second color space using the input adaptation data set and the prediction data set; using the at least one processor, generating a membrane forward color transform using the prediction error data set; and using the at least one processor, updating the forward color transform using the adapted parametric and nonparametric forward color transforms.
