摘　　要：为实现皮影服饰图案的自动提取,以唐山皮影头茬图像为例,分析了皮影服饰的色彩构成及图案特点,探讨了一种基于色彩聚类的皮影图案识别方法。通过相对总变差模型对皮影图像进行了噪声平滑处理;将处理后的数字图像由RGB颜色空间转换至CIE L*a*b*颜色空间,提取空间中的a、b两个色彩分量;利用K-means聚类算法对皮影图像色彩进行聚类分析,最终实现皮影色彩纹样的最佳分割。结果表明,笔者设计的算法可有效实现对于皮影这类色相分明、细节丰富且主色统一的彩色图像的分割。In order to achieve the automatic extraction of shadow puppetry costume patterns,taking the headdress images of Tangshan shadow puppetry as an example,the color composition and pattern characteristics of shadow puppetry costumes are analyzed,and a shadow puppetry pattern recognition method based on color clustering is discussed.Noise smoothing is performed on the shadow puppetry images through the relative total variation model.The processed digital image is converted from RGB color space to CIE L*a*b*color space.Two color components,a and b,in the space are extracted,the K-means clustering algorithm is adopted to carry out a cluster analysis on the colors of shadow puppetry costumes,and the best segmentation of shadow puppetry color patterns is realized finally.The experimental results show that the algorithm designed in this paper can effectively segment color images,like shadow puppetry color patterns,which have distinct hue,rich details and uniform main color.
