摘要：针对制作手工剪纸动画背景效率低、耗资大的问题，提出了一个计算机生成剪纸风格动画背景的方法。首先对构成手工剪纸动画背景的剪纸图案进行分类，包括种类繁多的树、花、草、山石、建筑等，然后用计算机方法生成这些模型。用户创作时，可从系统的剪纸背景图案库中导入所需模型放入指定位置，再通过少量交互，确定图案的大小方向以及各种其他属性。研究结果表明，采用此系统，通过将各类剪纸图案放入不同的位置，便可灵活且高效地组合出不同的剪纸动画背景图。

Abstract: Aiming that handmade Chinese paper cutout is an inefficient and expensive task, a method was proposed for generating animation background with the style of papercuts by computer to emulate handmade papercuts. First the papercuts graphics of animation background were classified with the style of papercuts, including a variety of trees, flowers, grasses, mountains, bridges, and so on. Then these models were generated by computer. Models could be chosen by users from the library of papercuts graphics, and be put into specified location, and their size, direction and other property were adjusted by a few interactions of users. The results indicate that adopting this method, users could build up a variety of animation background with the style of papercuts by putting different papercuts graphics into different location.
