Claim 16:
17. The method of claim 14, further comprising:
for each decoded codeword in the one or more first images, generating an output codeword in the one or more mapped images by performing:
initiating the output codeword to zero;
for each TPB basis function in the TPB basis functions, performing:
generating (n+1) non-zero B-Spline basis function output values for each channel in three channels of a color space, thereby generating three sets of (n+1) non-zero B-Spline basis function output values, wherein n indicates an order of the plurality of B-Spline basis function;
applying cross product operations to three sets of (n+1) non-zero B-Spline basis function output values to generate a TPB basis function output value from the decoded codeword in the one or more first images;
generating a product by multiplying the TPB basis function output value with a corresponding prediction parameter in the set of TPB prediction parameters;
adding the product to the output codeword.
