Abstract
A system is disclosed that uses input and output color space identifiers and other information about the transforms to automatically determine a size and a class of identity function composite tabular function. The identity function is constructed. The identity function is composed with input and output composite tabular functions to form a net composite tabular function. The identity function is selected based on the characteristics of the input and output spaces, color space, and transform shape. The size of the identity function is determined by the maximum size of the color space functions and the interval spacing that needs to be maintained for the net function.
