Researchers Use 3D Scan To Find Out Person’s Age
You may be able to guess a person’s age by examining the facial features but you may not be able to beat this tech at guessing. Researchers have found a way to guess person’s biological age by examining 3D scans of that person’s face.
Biological age is different from normal chronological age that we look at. It is defined as a measure of how well or poorly your body is functioning relative to your actual calendar age.
Biological age is a mystery and cannot be accurately calculated as it is somewhat a relative term. For example, your chronological age may be 60 years but because you have adopted a healthy lifestyle (such as avoiding tobacco and exercising regularly) throughout your life, your biological age may be 50 years.
The researchers at Chinese Academy of Sciences took up this challenge of finding out a person’s biological age by examining 3D features of face. They used a camera called the 3dMDface System to gather 3D images of 332 people in China with ages varying between 17 years old and 77 years old.
Next task in research was to detect patterns in these 3D scans that can help in finding out the person’s age. To detect these patterns, the team created a map of human faces which was then examined.
As we are already aware that facial features of a person changes as he or she grows older. The study revealed these changes in more detail. For example, the study found that as the person ages, the nose becomes wider, the mouth grows longer, the distance between mouth and nose increases, and the forehead narrows.
Moreover, the researchers said that corner of eyes also droop as the person grows older. Other patterns include young people having smoother faces and old people having thicker faces.
Using these patterns and some others, the researchers are able to detect person’s biological age with much accuracy.
“3D facial images can really tell your biological age,” said Jing-Dong Han in an interview with LiveScience. He further told that this method is even more accurate than a physical exam carried out by doctors.
The study reveals that biological age is different than chronological age by up to 6 years when the chronological age is below 40. After 40 years of age, this gap widens.
This research can come in handy in many domains. One use of this information would be that people who are aging physiologically faster compared to their actual age could be identified and given treatment to depending on their needs.
