This paper proposes a security pattern design. It is based on general M-J set image. By image vectorization methods, contours that are rich of fractal beauty are extracted for security pattern generation. Meanwhile EPS format vector graphic files are output that are compatible with universal image processing software for modification, color-filling or trapping. Experiments prove the generated security patterns to be complicated in structure,novel and fantastically looking. Such patterns can extend security pattern types.%提出一种安全底纹设计方法,该方法以广义M-J集分形图为基础,运用图像矢量化方法对其蕴含的富有分形之美的丰富轮廓信息进行提取,用于安全底纹生成,同时输出EPS格式矢量图形文件,可在各种通用图形、图像处理软件中对其进行修改、填色、陷印等处理,文件兼容性强.实验表明,该方法生成的安全底纹结构复杂、新颖且不失美观,扩充了安全底纹的类型.
