摘要
通常分形图不能用常规的平移、旋转和比例变换方法来进行仿射变换 .本文提出的系统方框图化简法 ,较好地解决了分形图形的平移、旋转和比例等仿射变换的问题 .该方法简明直观、计算方便 。
The normal methods of translation, rotating and scaling can not be applied to the affine transform of fractal images. This paper provides the method founded on the block diagram, which has been satisfactorily applied to solving the problem the affine transform such as scaling, translation and rotating of fractal images. With its simplicity and convenience for calculation, it will be suitable for more complicated multi transform.
