真实图形的颜色量化
COLOR QUANTIZATION OF IMAGES
-
摘要: 颜色量化是真实图形显示的一个重要环节.它的主要任务是将一幅有N个象素点的真实图用不超过K(K<<N)种颜色近似表示,以使这幅图能在颜色表长为K的显示设备上输出.本文提出了一种基于编码的颜色量化算法,此算法速度快,所生成的图形效果较好.Abstract: Color quantization is an important problem in rendering. The main task of color quantization is to approximate an image of N pixels with no more than K(K<
