在人脸漫画中,人脸特征(脸型以及五官)形状的夸张与特征之间关系的夸张是存在差异的,而目前由计算机生成的人脸漫画算法中并未考虑这一点,为此提出一种漫画夸张与合成方法.该方法由基于样本的特征的形状夸张、基于规则的特征之间的关系夸张以及两者之间的合成3部分组成.在人脸特征的形状夸张部分不需要大量的样本库,只通过少量的漫画样本便可以捕捉形状的夸张;在人脸特征之间的关系夸张部分,引入了直观的"T型规则"方式描述人脸特征在夸张时的相互关系;在人脸形状夸张与关系夸张两者的合成部分,采用"比例"的形式来描述人脸特征以及特征之间的关系,使得夸张后可以方便地进行两者的合成.最后采用调查问卷的方式评测该方法生成的漫画效果,结果表明其效果良好.

The difference between shape exaggeration and relationship exaggeration of face features has been seldom considered in existing algorithms of caricature generation. A new method for caricature exaggeration and synthesis is proposed in the paper, covering shape exaggeration, relationship exaggeration and global synthesis. Rather than relying on a large training set of caricature face pairs, the shape exaggeration step is based only on several caricature examples to capture the shape exaggeration. T-Shape rule is introduced in the relationship exaggeration step, to describe the relative relationship between the facial elements in an intuitive manner. A description method is introduced in the synthesis step, in characterizing the facial features in a proportion form. Besides, an anonymous questionnaire survey has been undertaken to evaluate the generated caricature with this method. The results show the effectiveness of the method.
