Discover age guessing technology through photos

Most people know that the results are not completely accurate (at the age of guess). Many people are "judged" older than their actual age, others are younger.

Technology guesses age through photos of How-Old.net

Over the past few days, there have been millions of photos uploaded to How-Old.net to guess the age and gender of the person in the picture . Most people know that the results are not completely accurate (at the age of guess). Many people are "judged" older than their actual age, others are younger. Of course, there are also cases where Microsoft Face API technology guesses correctly.

However, some health professionals view the results of How-Old.net as a " diagnostic" of your health status.

But first, learn how Face API works. First, this program will identify face recognition areas that are in the photo you upload. This process is mainly based on whether or not it finds your eyes .

In most cases, Face API found eye positions, but there were some exceptions. This is why some uploaded photos return results that cannot be found, especially if people in the picture wear sunglasses or upload black and white photos.After the identification process is completed, the new Face API splits the facial positions to determine the age. For example, separating the location of iris, eye-tail, eyebrows, lips, wrinkles, etc. The program also tests some "old age " simulations by changing colors or lines face. From there will show the age figure placed above each face.

In theory, it is clear that the operating principle of Face API is highly accurate. But why do many images return false results?

There are 2 reasons. The first reason is because the photos that the user uploads do not show the full face, only partially or not taken in the frontal corner. It is also possible that the light conditions during shooting do not accurately represent the person's actual skin color. Or maybe it was because the photos were edited through "beauty salon" technologies. Many women take photos with third-party apps like Camera360 and use a range of filters and effects. However, providing " too difficult" information cannot require the system to return accurate results.

Face recognition is a complex process with computers.

But the other reason is the most important. In case you download photos without editing, photos from the front and show the full details, but why the figure that Face API returns is still incorrect? If so, try different photos and try asking friends around you if you look old or young. And the answer from them is worth thinking.

In fact, not everyone of the same age always has an "old" face . Some people look older than their actual age, whereas others look younger than their actual age. Not long ago, the online community once buzzed about a Japanese female MC who was over 40 years old but the young face is still " twenties ". Suppose if this woman walked down the street next to the 9x girls, maybe you still thought they were you - you, not aunt -. Japan is also known to be the world's longest-lived nation.

But what do those numbers say?

Richard Russell, a professor of psychology at Gettysburg Academy, who studied the relationship between age and face (but independent of Microsoft), said: "There is one fact that the wrinkles often appear At the same time with old age, we don't know why, but what you look like is how to predict life quite accurately . Many studies have also shown that people with older faces before age often die earlier than those who look younger than their age.

Perhaps this cute 27-year-old girl will live very long.

In fact, the process of assimilation and catabolism has a close relationship with human lifespan. In children and adolescents, a stronger assimilation process leads to faster regeneration and construction of new cells. Young children also often heal wounds faster than adults. In adults, the process of catabolism takes place more strongly, fewer new cells are formed and ultimately makes wrinkles appear more. However, in some people, it seems that the assimilation and catabolism stage does not "mix" with people of the same age, so they look older or younger than their actual age.

According to experts' recommendations, people need to keep their bodies healthy, less exposed to stimulants, less oxidized by cells or exposed to environmental pollution. And if the photos you post on How-Old.net are completely " rustic" pictures, they have not been used for makeup or editing, the number of ages you will receive will be higher.
