Paper Abstract

In the measurement of color, such as interference colors of birefringent crystal and color of the pseudocolor encoded output image(1),metamerism is a very widespread phenomenon, which influences directly practical applications of the meauement"and discrimination of color. In this paper, in order to research a one-to-one relation between color and object to be recognized, a 4-D generalized chromaticity space is presented and "the machine color" of birefringent crystal is measured and calculated. The results show that the metamerism can be distinguished efficiently by this method, which would be of significance in real-time automatic color discrimination.
