MEASURE OF GOODNESS OF A SET OF COLOR-SCANNING FILTERS

Accurate scanning of a color image, which is absolutely essential for good color reproduction, can ensure that all relevant information abou t the color stimulus of a signal is obtained. The set of scanning filt ers is hence an important component of a color reproduction system. In this paper we introduce a measure of the goodness of a set of color-s canning filters. This measure relates the space spanned by the scannin g filters to the human visual subspace. The q factor of a single color -scanning filter is shown to be a particular case of the measure. Expe rimental results are presented to justify the appropriateness of the m easure.
