Abstract
Tuning sizes of cells of an interpolated lookup table may be performed based at least in part on an area specific behavior of a quality metric. A weighted input shaper curve may be determined to reduce interpolation errors in a multi-dimensional color lookup table. An initial input shaper curve may be applied to a color lookup table to create an interpolation result. The interpolation result may then be assessed for accuracy. The accuracy assessment may include comparing the interpolation result with a reference representation. An interpolation error may be calculated as the error between one or more intervals in a prospective color lookup table as compared to a reference representation. The weighted input shaper curve may be based at least in part on the calculated interpolation error.
