Abstract
Color calibration involves the assessment of a tristimulus vector describing a surface. A color calibration device must return this tristimulus vector under various surface modes and/or illuminants. For reflective surfaces, the illuminant must be known in order to assess the surface reflectance. For luminous surfaces, a pseudo-illuminant may be used to account for the adaptation state of the observer. In each separate case, the color calibration device requires a different set of color matching functions. These several sets do not span a single three-dimensional space. Ideally, a device capable of operating under k modes should have basis functions spanning a 3k dimensional space. This paper considers the selection of fewer than 3k basis functions for operation under k modes. It discusses the selection of error criteria and a strategy to minimize the error due to the reduced dimensional approximation.
