From: Generating Chinese intangible cultural heritage images with structure and color awareness
This figure illustrates the hierarchical taxonomy and metadata schema of representative intangible cultural heritage (ICH) projects in Henan, categorized by artistic form: New Year Picture, Clay Sculpture, Paper Cutting, Embroidery, and Palace Lantern. Each style entry includes detailed project provenance (region, institution, and batch year), visual features, and the number of documented samples (N). On the right, four types of annotated metadata—pattern, modeling, process, and color—are illustrated. These metadata styles are not exclusive to any specific artistic form but are shared annotation dimensions applicable across different ICH styles. For example, both paper cutting and embroidery may contain animal patterns or geometric motifs, and all styles involve color characteristics, such as main color, decorative color, or traditional symbolic palettes. This structure supports a style-aware and interpretable modeling framework.
