Abstract: Referring to the needs fabric patterns preserve traditional national styles, digital design of Uygur carpet patterns are taken as an example. This paper puts forward a CAD-scheme of the computer-aided design technology of textile patterns, and illustrates three important stages: First, by using template matching algorithm to extract the pattern elements in the same category, a different types of gene databases are picked-up and created. Second, these skills of path decoration and paint preset are implemented carpet patterns design based on PhotoShop. Third, the techniques are combined to form synthesizer of carpet design. The proposed method is closely keeping the national style of design and carried through with typical Uygur carpet.
