Wavelet decomposition based representation of nonlinear color transformations and comparison with sequential linear interpolation

A wavelet decomposition based surface compression technique to represent the forward transformation for a color printer is presented. The method creates a multi-scale grid structure for a given maximum pointwise error threshold. The error performance, the memory requirement, and the computational cost of this technique are compared with those of minimax sequential linear interpolation (SLI) and minimum mean-squared (MMSE) SLI.
