It's not easy to distinguish between real or fake smiles or facial expressions, but researchers have now developed a special computer software that can recognize fake expressions. A study published in the Journal of Advance Engineering Informatics says that the software can explain the changes that occur while smiles on one's face. Let's know the full details
For your information, the study says that the software has seen the most important movements and movements near the eyes during this time. This proves to be true of the old theory that spontaneous and genuine laughter is visible in the eyes of the frontman. Author Hassan Ugel, professor and lead professor of studies at the University of Bedford in the UK, said: "In the past few years, technology that has been able to understand the facial expressions of human beings has grown rapidly, but it has always been a challenge to distinguish between real and fake smile expressions because we focus on very small changes. Can't give up.'
The software first mapping the face of the person appearing in the video and identifies the mouth, cheeks, and eyes of the subject. It then understands how many movements the face appeared in the video clip for an expression or smile. It detects whether the expression was genuine or fake, with the number of movements or changes calculating during smiles. Researchers tested the program with the help of two different databases. One had real laughing faces, while the other had a fake smile.
According to media reports, researchers found that the program found a big difference between the changes in the mouth and cheeks of faces with a real and fake smile. The biggest difference was the look around the eyes of the subjects and during the real smiles, these muscles show about 10 percent more movement. "We mainly use two parts of the muscles when smiles," Said Ugel said. One is the zygomaticus major, which pulls the mouth upwards and the second is the orbicularis oculus, which makes the eyes smaller.' Researchers say that during a fake smile, the muscles of the mouth move, but there is not much change around the eyes. "Understanding whether one's smiles or expressions are real can help us in many ways. For example, in biometric identification, the interaction between computers and humans can also be improved in this way," said Ugel. It is understandable that users are really happy with the computer service or are only pretending to be," he said.
