Abstract: In this paper we first analyze the form of hand-made Chinese paper cut-out of animal figures and decompose them into different decorative patterns, then we construct corresponding vectorization patterns to form a paper cut-out pattern bank. During the creation process, the user first composes the outline of the paper cut-out image, and then picks up some patterns from the bank to fill the space inside the paper cut-out image. Potential applications of the system are the design of decorative pattern, electronic card, advertisement, game and animation.
