一种多风格人脸卡通画样本的形状绘制参数编码
首发时间:2010-03-01
摘要:本文提出了一种基于形状的人脸卡通画参数化编码方案,实现不同风格人脸卡通画样本的统一参数化表示。该编码方案通过绘制分层、矢量化表示和形状驱动解决了多风格人脸卡通画样本的表示和再呈现问题。利用该编码方案,我们构造了一个人脸卡通参数化样本空间,包括人脸特征的参考形状定义(RPD)和针对卡通画的绘制参数定义(RSD)。给定一个人脸图像,经过样本学习获取人脸卡通画的绘制实体和绘制规则,完成卡通人脸的自动建模。依据卡通人脸模型,绘制引擎能自动绘制合成艺术化的人脸卡通画图像。

A Parametric Representation for Cartoon Sample Space
Abstract:In this paper, a novel shape-driven parametric model for facial cartoons is proposed which supplies a unified method for representation and organization of facial cartoons. Samples consisting the faces and the corresponding facial cartoons drawn by artists are parameterized according to the proposed cartoon face model, forming the painting parameter definition (PPD) and the reference shape definition (RSD). And tow conversions constitute the maps between RSD and PPD. Using the cartoon sample space, the parametric representation and organization of the samples across different styles can be resolved in a unified framework, which forms the basis for automatic cartoon face modeling and facial cartoon rendering based on the sample learning.
