| Abstract(in English) | In a 24 bit full color image, there are about 16 millions possible colors. On the other hand, in a limited color image, the color of each pixel is selected from a color pallet which contains very few colors. The colors in a color pallet are called representative colors. A limited color image has smaller file size than a full color image. In order to generate limited color images with small file size, it is necessary to decrease the number of representative colors. However, colorful colors may disappear by reducing representative colors and the quality of the image may be severely degraded. In this report, we propose a color quantization method based on the wighted principle component analysis using saturation. In the proposed method, colorful colors are selected as representative colors preferentially by using saturation as weights. Through experiments, we verify the effectiveness of the proposed method. |
