ABSTRACT:
A color printing/display system includes a representation for approximating color space transformation comprising a set of piecewise homeomorphisms for enhancing accuracy of parametric models associated with the homeomorphisms. The homeomorphisms and parametric models are selectively adjustable in accordance with printer/display calibrating data. Preferably the piecewise sub-spaces comprise corresponding simplices with domain and co-domain color spaces. The simplices are adjusted by calculating new locations for the vertices having a consequence of converging parametric model performance in accordance with the predetermined objective of the system.
