Abstract
A method of performing color conversion to convert a set of input color values to color values in an output color space includes representing an output color in the output color space as a geometric lattice having a plurality of lattice points, each of the plurality of lattice points having an address defined by a particular set of input color values; using a set of input color values with respect to the geometric lattice to determine a set of lattice points that neighbor a point corresponding to the set of input color values to be interpolated; choosing a random number; and utilizing the random number to select a first lattice point of the set of lattice points to provide as a pseudo-interpolated result of the color conversion.
