摘要
分析了徒手画曲线的性质,提出了徒手画曲线的主曲线概念,并提供了一种搜索该主曲线的折线逼近算法,自适应地得到主曲线;试验证明:算法得到的主曲线能抓住原徒手画曲线的特征,去除了原曲线的噪声,反应绘图的愿望,并且确定该主曲线的数据点较少。
This paper analyzed the character of sketch curve and developed the concept of principal curve of sketch curve, and provided an adaptive algorithm by polygonal line for approximating principal curve. The experimental results show that the gained curve by using the algorithm is smooth and can hold original curve's character, remove the noise, represent drawer's intention. Moreover, the points are relatively fewer that confirm the principal curve. All these suggested the practicality of the adaptive method. Furthermore, the algorithm can be applied to surface design in CAD,and enhance the ability of man-machine interaction .
