Abstract (in Japanese) (See Japanese page) 
(in English) In this report, a new color quantization method, which is an improved median cut algorithm by considering the color distribution, is proposed. In the proposed method, the color quantization is achieved by the iterative pixel set dividing based on the principal component analysis (PCA) and the linear discriminant analysis. Concretely, at first, PCA is applied to a pixel set in the RGB color space, and the first principal component scores are calculated. Then, the set is divided by a plane in the RGB color space so that the separability of the scores becomes maximum. This procedure is repeated until the number of pixel sets becomes equal to the required one. Finally, the average color of each pixel set is obtained as the representative color and the color quantization is realized by using it. In the experiment, various images are employed, and the resultant images are evaluated subjectively and objectively in order to verify the effectiveness of the proposed method.
