摘要
由于难以控制视频反馈的混沌效应,目前还未有基于视频反馈的图案创作工具。针对这一问题,把图像滤波及交互式仿射变换的技术引入视频反馈,构成一种基于视频反馈的交互式图案创作系统。用户可以方便地定义视频反馈中的图像处理运算,以绘图方式定义复合的平面仿射变换,运用实物以可触式交互的方式生成多变的分形图案。实验结果表明,该系统交互性良好、创作效率高、结果多样化,能够高效地生成多样化的符合特定主题的分形图案。
Because it is difficult to control the complex chaotic behaviors of the video feedback mechanism, no video feedback based pattern-design system exists. An interactive fractal pattern generation system, namely the VFPD (video feedback pattern designer), was presented. Various image filters and affine mapping were integrated to facilitate the pattern definition process in the video feedback loop. The user can create diverse fractal patterns by tangible interaction. The results show that the proposed method and system can effectively and efficiently generate fractal patterns in different styles and structures.
