Pattern Recognition:美丽面容的量化评价方法
人们常说“美不美,只有眼睛知道”,美只是一种主观感受。但美国研究人员最近发现美貌也可以量化,进行科学地评价。相关报道在线刊登于2007年12月的爱思唯尔期刊《模式识别》(Pattern Recognition)上。
参照以往的研究基础,研究人员设计了综合多种因素的面部吸引力量化评价方法。研究人员安排来自内布拉斯加大学林肯分校的36名志愿者(男女各半)为232张白人(高加索人)面部图像进行评分,满分为10分。然后,研究人员对打分结果进行计算机分析,重点关注男性和女性志愿者都是如何评价面部吸引力的。同时,他们还试图发现美丽面孔的共性特征。
研究结果显示,男性和女性志愿者对美丽面容的评价基本一致,不同之处在于男性志愿者给出的分数普遍高于女性志愿者。另外,总体来说,女性面容图片比男性面容图片得分高,可能的原因是女性面貌特征更具有吸引力。具体说来,小的下巴和鼻子,两眼之间距离大一些,小嘴都能让女性更显娇美。而对男人来说,眉眼和嘴将面部竖直方向上三等分将更显英俊。此外,嘴唇上沿和鼻子的对称也是英俊面孔的要素之一。
这项研究提出了评价面容吸引力的模型,表明了几何学在面容吸引力评价上的重要作用。(科学网 荔涛/编译)

Abstract
Analysis of attractiveness of faces has long been a topic of research. Literature has identified many different factors that can be related to attractiveness. In this research we analyze the role of symmetry, neoclassical canons, and golden ratio in the determination of attractiveness of a face. We focus on the geometry of a face and use actual faces for our analysis. We find there are some differences in the criteria used by males and females to determine attractiveness. The model we have developed to predict the attractiveness of a face using its geometry is accurate with low residual errors.
