Artificial intelligence AI can distinguish sex according to smile
Artificial intelligence AI can distinguish sex according to smile
New studies have shown that artificial intelligence can distinguish women from men according to their smiles. This is because a woman's smile is more extensive than a man's smile. This discovery enables researchers to create an artificial intelligence algorithm that can quickly identify gender. Professor Hassan Ugail, who is responsible for the research, said, "interestingly, women think their smiles are more expressive, and our research has confirmed this. Women have a wider smile, and the area of lips enlargement is far more than that of men".
This method looks at the movement of the face in a smile rather than using a static image. It is considered the first job in the field. It works by tracking the movement of 49 points on the face. These "landmarks" are mainly close to the eyes, the mouth and the nose. The team analyzed 109 people, including 69 women and 40 men.
This system can measure facial muscle movement during smiling. This face recognition technology can become the next generation of biometric technology, because it does not rely on a specific feature, but is mainly based on the unique dynamic characteristics of the individual, and it is difficult to imitate or change. The team believes that the current algorithm success rate can be improved, because now they just days after the test of this concept, more complex AI can improve the recognition rate.
However, the study has raised questions about gender identity and cross gender, and the team hopes to solve this problem through more research. The group pointed out that gender cognition plays an important role in "facial cognition, age, race, identity analysis, video surveillance and intelligent human-machine interaction".
