前不久,中科院上海生科院计算生物学研究所的一个研究组从面部衰老着手,发现由人脸三维面部细节的衰老趋势可以精准预测一个人的生理年龄。研究人员使用3D相机在北京疾控中心随机采集了年龄在17岁到77岁之间的332个中国人的三维面部图像,定量分析结果显示:人的年龄可以真实地“写”在脸上,嘴的宽度、鼻子的宽度、嘴与鼻子之间的距离以及眼角的下垂程度是衰老最明显的迹象。随着年龄的增加,这四项指标均会出现明显增加。研究人员还发现:40岁以前,计算机预测出的样本年龄与其实际年龄的差距平均在6岁左右,而40岁以后的差距
Not long ago, a research group at the Institute of Computing Biology, Shanghai Institutes of Biological Sciences, Chinese Academy of Sciences, started from facial aging and found that the physiological aging of a person can be accurately predicted by the aging trend of three-dimensional facial details of a human face. The researchers used a 3D camera to randomly capture 3D facial images of 332 Chinese aged 17 to 77 years at the Beijing Center for Disease Control and Prevention. The quantitative analysis showed that the age of a person can be truly “written” in the face The width of the mouth, the width of the nose, the distance between the mouth and the nose, and the degree of drooping of the corners of the eyes are the most obvious signs of aging. As the age increases, all four indicators will show a significant increase. The researchers also found that: before the age of 40, the average age gap between the predicted age of the sample and its actual age by computer was about 6 years old, while the difference after age 40
