Researchers at the University of Bradford in the U.K. have developed an artificial intelligence (AI) system that identifies gender by reading a person's smiles.
The team mapped 49 facial landmarks, mostly around the eyes, down the nose, and close to the mouth. They employed the landmarks to evaluate how the face changes as people smile due to underlying muscle movements, including both changes in distances between the different points and the "flow" of the smile.
The next step was analyzing whether or not there were differences between women's and men's smiles.
"Anecdotally, women are thought to be more expressive in how they smile, and our research has borne this out," says Bradford professor Hassan Ugail. "Women definitely have broader smiles, expanding their mouth and lip area far more than men."
An algorithm was tested using video of more than 100 people smiling, and the AI ascertained gender correctly 86% of the time.
