基于特征变形的人脸肖像漫画生成

Generating algorithm of portrait cartoon based on feature deformation

漫画以极度夸张和变形的手法来表现人物,使其人脸特征更为突出.通过分析传统人脸肖像漫画的作画规律,提出使用基于特征线段和鱼眼放大挤压算法的人脸肖像漫画生成算法.实现交互拾取肖像人脸的关键特征点、整体的拉伸压缩变形方式以及局部的鱼眼变形方式,使得普通用户也能生成个性化的人脸肖像漫画,大大减少了手绘的工作量.所生成的漫画风格人脸肖像效果良好,能够应用于电视动画节目、网络和报刊杂志等非真实感图形学和数字娱乐等领域中.

The portrait cartoon is used to express a personality using exaggerated and deformable method, which can make the facial features more attractive. A generating algorithm of portrait cartoon based on eigenvector and fish-eye algorithm is presented by analyzing the sketching law. It can be realized through obtaining key feature points interactively, stretching or compressing the whole portrait, and using fish-eye deformation algorithm partly. The general users also can generate personalized portrait cartoon using this method, which can reduce the hand-drawing workload. The generated portrait cartoons are effective and vivid. They can be applied in non-photorealistic computer graphics and entertainment, such as video, network, newspapers and magazines.
