Abstract: Xinjiang ethnic fabric pattern with particular cultural connotation is an important
part of Chinese national art treasures. To address how to use computer to generate fabric patterns
with Xinjiang ethnic features and style is a challenging problem. A new extraction algorithm of
pattern gene based on feature selection and primitive pattern filtration is proposed and the
practicality of the method is testified. First, connected region is marked to carry out pattern
segmentation for primitive pattern, pattern features are extracted to calculate features ratio and
choose vote principle to filter primitive pattern for pattern genes. Then, Xinjiang ethnic fabric
patterns are generated based on pattern genes and hexagonal structure. The experiments are carried
out by extracting pattern genes in Uygur and Kazak fabric patterns based on the segmentation
method and generating Xinjiang fabric patterns by geometric transformations of hexagonal tile,then the similarity of of design style is evaluated. The proposed method is able to quickly generate
a large number of patterns with different national features. It can not only enrich design style sets,
but also provide a new way to inherit ethnic heritage designs.

Key words: pattern gene, feature filtration, hexagonal tile, style design
