基于K-means聚类的马王堆帛画色彩特征分析与应用

Analysis and Application of Color Characteristics of Mawangdui Silk Paintings Based on K-means Clustering

目的 提取马王堆帛画特征色彩,分析帛画色彩间配色关系,为文创产品设计的配色过程提供指导,在设计中更加准确地展现帛画的文化特色。方法 首先使用优化后的K-means聚类算法提取出帛画的特征色彩,生成帛画的标准色卡;然后利用图像中的色彩占比数据和色彩邻接关系,建立色彩网络模型,确定色彩主辅色搭配;最后利用CorelDRAW插件colorshuffle自动生成多个配色种群,使用模糊综合评价方法验证帛画特征色彩提取的可行性与运用色彩网络模型辅助配色的可操作性。结论 使用K-means聚类方法提取出的帛画标准色卡应用于设计时具有色彩代表性,构建色彩网络模型和插件辅助配色能够提高设计师的配色效率,为文创产品的配色设计过程提供了新的思路。

The work aims to extract characteristic colors of Mawangdui silk paintings,and analyze the color matching relationship between silk paintings,so as to provide guidance for the color matching process of cultural and creative product design and show the cultural characteristics of silk paintings more accurately in the design.The optimized K-means clustering algorithm was used to extract the characteristic colors of silk paintings,and a standard color card of silk paintings was generated.Then,a color network model was established with the color proportion data and color adja-cency relationship in the image,and the matching of primary and secondary colors was determined.Finally,a number of color matching populations were automatically generated by CorelDRAW plug-in color shuffle,and the feasibility of ex-tracting characteristic colors of silk paintings and the operability of assisting color matching with color network model were verified by the fuzzy comprehensive evaluation method.The standard color card of silk painting extracted by K-means clustering method is representative in color design.Building a color network model and plug-in assisted color matching can improve the color matching efficiency of designers and provide a new idea for the color matching design process of cultural and creative products.
