基于遗传算法的剪纸图案创新设计

Creative design of paper cut-out based on genetic algorithm

通过对剪纸造型的分析和概括,抽象出所需的纹样,利用遗传算法来生成纹样,并且在适应度函数的构建方面,增加了对曲线均匀度和平滑度的度量,以此构造丰富多彩的纹样库。然后通过对剪纸造型结构上的分析,对纹样库中的各种纹样进行自动选取及组装,产生各种各样风格不同的剪纸图案造型,并可根据实际需要进行人工修改。实验证明,该方法能够增强剪纸图案设计的创新性。

Through the analysis and summation of the paper cut-out,this paper first abstracts the needed patterns and uses the genetic algorithm to generate them,and it increases the measurement of the curve uniformity and smoothness on the founding of the fitness function so as to found a colorful pattern bank.And then through the analysis of the paper cut-out’s structure,it selects and assembles the various patterns in the bank automatically to create all kinds of different styles of the art patterns which can also be manually changed according to the actual needs.The method above has been proved in the experiments that it can enhance the creativity of the paper cut-out design.
