Abstract: By analyzing the geometric features and visual characters of Q-style cartoon figures, an image-based method for computer simulation is proposed, which deforms the figures according to the figures’ photo and key parameters, and imitates the Q-style cartoon figures created by artists. The part-magnifying algorithm based on parspl spline curve is also put forward to solve the problem that the head of figures is out of shape, which enhances the visualization. This method needs little parameter, and is easy to control, fitting in the fields of animation and digital entertainment.

Key words: non-photorealistic rendering, Q-style cartoon figures, parspl spline curve, deformation

摘要： 通过分析Q版卡通人物的几何特征和视觉特点，提出一种基于图像的计算机仿真方法，根据用户输入的人物照片和关键特征点对人物进行变形和卡通风格化，以模拟艺术家绘制的具有夸张效果的Q版卡通形象，提出基于抛物样条的局部放大算法，该算法能有效解决人物头部变形问题，增强可视性。该方法所需参数少，算法简单，易于控制，适合漫画制作和数字娱乐等领域的应用。
