摘要
在色彩量化问题中,对颜色层次感和关键细节的处理是一个困难的问题.如果保留颜色层次感,就会失去关键细节,反之亦然.针对该问题提出了一种新颖的基于颜色差异(Color-Difference,CD)的颜色量化算法.该算法即可以保留颜色层次感,又可以保留关键细节.
How to choose the colors that present the color layers of the image as well as the colors that present the essential details of the image is a difficult problem.If you want save more color layers,you will loss details,vice versa.In this paper,we propose a novel color quantization algorithm based on color-difference（CD）,which could reserve the color layers as well as essential details.
