基于路径的图像变形算法

针对计算机辅助图案设计系统中基于路径的图像变形问题，提出了通过构造笛卡尔坐标系来建立变形映射关系的算法。探讨了两种变形方式：柱状变形和带状变形，并利用带状变形模拟了一种双面带的变形效果。对路径剧烈转折时柱状变形效果差的弱点，采用了一种限制映射区域的变形方法，改善了图像剧烈弯折时的变形效果。另还讨论了图像的反混淆问题，并结合变形算法，提出了一种基于平滑直线的图像反混淆算法。

Path-based image metamorphosis computer graphics

In this paper, we bring forth a way of building up metamorphosis computer graphics through constructing Descartes reference frame, which is aimed at the path based image metamorphosis and computer graphics in the computer aid design system. We also propose two ways of metamorphose: mast metamorphose and strip metamorphose,simulate double face strip metamorphose effect by using strip metamorphose; and adopt a metamorphose method which can confine the mapping region to lessen the mast metamorphosis's bad effect in the acute transition. To turn over image confusion we suggest a counter confusion computer graphics based on the smoothed line.
