Abstract
Color image can be classified into different object areas with clustered color distribution. After the classification process, each object area is characterized by Principal Component Analysis. The a^* and b^* are predicted by the projection of L^* onto chromatic plane using the eigen vectors of covariance matrix and the mean vectors. Finally, the full color image is reproducted by combining the luminance with (a^*,b^*)
