Gender and age can be determined from face silhouettes
Rockville, MD ?A new study published in Journal of Vision demonstrates that face silhouettes are visually processed much like regular face stimuli and provide enough information to determine traits about the subject including age and gender.
Researchers from Stanford University conducted a variety of studies using silhouetted face profiles obtained by reducing gray-scale photographs of face profiles to two-tone black and white images. Study participants were asked to determine the gender and age of the individuals in silhouette. Results showed that people can extract information from silhouetted face profiles about their front-view counterparts.
Male silhouettes were classified as male 83.3 percent of the time and female silhouettes were classified as female 55.7 percent of the time. Researchers believe the difference in accuracy can be attributed in part to the lack of hair on the silhouettes which may be perceived as baldness, a possible cue to maleness. Over 68 percent of respondents selected the correct age-range for the silhouettes, compared to a chance level of 38.8 percent.
揗ost research on face perception focuses on the role of features such as the eyes, the nose, and the mouth,?said lead researcher Nicholas Davidenko, PhD. 揙ur studies demonstrate the importance of shape in face recognition. By using mathematically defined face silhouettes, we have discovered the types of shape variations that determine the gender, age, and distinctiveness of a face.?/p> 本人已认领该文编译，48小时后若未提交译文，请其他战友自由认领。 发布日期：

根据脸部轮廓可判断性别与年龄

Researchers from Stanford University conducted a variety of studies using silhouetted face profiles obtained by reducing gray-scale photographs of face profiles to two-tone black and white images.通过将脸部的灰度肖像照片简化为只有2种色调的黑白图像，斯坦佛大学的研究人员们对得到的脸部肖像轮廓进行了一系列研究。 Study participants were asked to determine the gender and age of the individuals in silhouette.要求研究参与人员们对轮廓中的个人的性别与年龄作出判断。 Results showed that people can extract information from silhouetted face profiles about their front-view counterparts.结果表明人们可从正面肖像照片的脸部轮廓推断出相关信息。
Male silhouettes were classified as male 83.3 percent of the time and female silhouettes were classified as female 55.7 percent of the time.男性轮廓有83.3%可被归类为男性，而女性轮廓有55.7%能被归类为女性。 Researchers believe the difference in accuracy can be attributed in part to the lack of hair on the silhouettes which may be perceived as baldness, a possible cue to maleness.研究人员们相信，之所以在判断准确性方面会有差异，可部分归功于有些轮廓图中没有头发，可被察觉为秃头，这是可能是男子的线索。 Over 68 percent of respondents selected the correct age-range for the silhouettes, compared to a chance level of 38.8 percent.有超过68%的回答者为那些轮廓图选中了正确的年龄范围，与此相比，偶然猜中的只有38.8%。
揗ost research on face perception focuses on the role of features such as the eyes, the nose, and the mouth,?said lead researcher Nicholas Davidenko, PhD.研究领导者Nicholas Davidenko博士说，大多数对脸部识别的研究焦点集中在如何利用诸如眼睛、鼻子及嘴巴等特征上。 揙ur studies demonstrate the importance of shape in face recognition.我们的研究证明了脸部识别中脸型的重要性。 By using mathematically defined face silhouettes, we have discovered the types of shape variations that determine the gender, age, and distinctiveness of a face.?/p>通过使用数学定义的脸部轮廓图，我们发现了可判断性别、年龄及脸部不同特征的形状参数类型。
