基于聚类分析的色彩量化新算法及其应用
A New Clustering Algorithm for Color Quantization and Its Applications

摘要: 针对针织提花、植绒、印染以及金属表面花纹处理等电脑设计中的要求,研究彩色图像重新量化成仅有几种颜色的色彩量化问题,提出一种基于聚类分析的色彩量化新算法,量化图像较好地兼顾了原图像的总体风貌和设计者希望保留的一些特征.该算法计算量小,容易在微电脑中实现,已成功地应用于电脑提花圆机花型CAD系统.该算法对一般的色彩量化问题也具有重要意义.Abstract: Two approaches of generating offset surface of helicoid is proposed: directly from helicoid,and from the offset section curve.Aconcept of section offset surface is introduced.The relationship of two offset surfaces is discussed.Finally,an example illustrates their difference.
