动漫化人脸生成下的角色面部夸张要点分析

Facial Exaggeration Points of Characters under Animation Face Generation

针对我国当代动画人物面部夸张本土化不足的问题,尝试在夸张趋向上进行认知和方法的突破。通过分析东西方动画人物设计夸张的差异性,指出当代中国动画在夸张方法上的缺陷和可突破重点。借助动漫化人脸生成平台,从真人照片快速生成大量动漫化人脸,在对比分析及人工干预的基础上,归纳生成夸张要点和其在动画人物设计中的应用,并根据东亚人种头面部特征和中国传统面相学理论探讨其他影响本土动画人物设计面部夸张因素。“普遍加大眉眼间距”“普遍保留或夸张不对称性”是动漫化生成过程中体现出的适配本土动画人物设计的生成夸张要点;此外,还应当在“脸型的几何化夸张”“五官的性格化夸张”“添加中国面孔常见的细节特征”“年龄性的夸张”和“美术风格的夸张”等方面进行多样化夸张设计;AI生成的方法能够为动画人物设计提出可借鉴的思路,但AI生成在艺术设计研究中的应用离不开传统文化理论和艺术家的指导。

The work aims to address the lack of localization in facial exaggeration of contemporary animated characters in China and to attempt to make a cognitive and methodological breakthrough in the exaggeration tendency.By analyzing the differences between the exaggeration of animated character design in the East and the West,the shortcomings and the key points for breakthrough of contemporary Chinese animation in exaggeration are pointed out.With the help of the animation face generation platform,a large number of animation faces are quickly generated from real-life photos.And based on comparative analysis and manual intervention,the key points of generative exaggeration and its application in animated character design are summarized.According to the heads and faces features of East Asian race and the traditional Chinese facial science theory,other factors influencing facial exaggeration in local animated character design are explored.The conclusion is that"increasing the distance between the eyebrows and eyes universally"and"preserving or exaggerating asymmetries universally"are generative exaggerated points in animation generation that are suitable for local animation character design.In addition,there should also be a variety of exaggerations in the areas of"geometric exaggeration of the face","characterized exaggeration of the five sense organs","addition of details common to Chinese faces","exaggeration of age"and"exaggeration of the art style".And while AI-generation methods can suggest ideas that can be drawn upon for animated character design,the application of AI-generation in art and design research cannot be done without the guidance of traditional cultural theories and artists.
