苗族抽象植物纹样数据库

苗族抽象植物纹样多源于自然植物，如牡丹、石榴、桃花等，经过提炼加工，将植物的核心特征抽象化。例如把枫叶抽象为菱形，用简单的几何形状来代表植物的形态。色彩搭配规律苗族传统纹样色彩搭配具有鲜明的特色
运用设计符号学，从语意、语构、语境、语用四个维度对苗绣纹样元素进行分析，建立基础纹样库。根据设计要求和图案特性，制定形状推演规则，通过对纹样进行矢量图分解，利用形状文法的推理规则，如镜像、旋转、重复、删减等，矢量化提取算法：运用大规模矢量

Most abstract plant patterns of the Miao ethnic group are derived from natural plants including peonies, pomegranates, peach blossoms and others. After refinement and processing, the core features of these plants are abstracted. For example, maple leaves are abstracted into rhombuses, with simple geometric shapes representing the plant's morphological features. Color matching rules: The color matching of traditional Miao patterns exhibits distinct characteristics. Adopting design semiotics, elements of Miao embroidery patterns are analyzed from four dimensions: semantics, syntactics, context and pragmatics, and a basic pattern database is established. Shape deduction rules are formulated based on design requirements and pattern properties. Through vector graphic decomposition of the patterns and leveraging inference rules of shape grammar such as mirroring, rotation, repetition, deletion and others, the vectorization extraction algorithm is applied, which utilizes large-scale vector
