By analyzing the movement of the smile across a person’s face, the software developed by researchers at the University of Bradford can determine whether or not the expression is true. The most significant movements detected by the software were around the eyes, supporting popular theories that a true smile is one that can be seen in a person’s eyes.

“A smile is perhaps the most common of facial expressions and is a powerful way of signaling positive emotions (情绪)” says Hassan Ugail, Professor of Visual Computing at the University of Bradford, who led the research. “Techniques for analyzing human facial expressions have advanced a lot in recent years but distinguishing between true and false smiles remains a challenge because humans are not good at picking up the relevant messages.”

The software works by first mapping a person's face from within a video recording, and identifying the mouth, cheeks and eyes of the subject. It then measures how they move through the progress of the smile and calculates the differences in movement between the video pieces showing true and false smiles. They found significant differences in the way the subjects' mouths and cheeks moved when comparing the true and the false expressions. The movements around the subjects’ eyes, however, showed the most striking difference, with true smiles producing at least 10 percent more movement in these muscles (肌肉).

“We use two main sets of muscles when we smile — the zygomaticus major, which is responsible for the movements upwards of the mouth and the orbicularis oculi which causes movements around our eyes,” explains Professor Ugail. In false smiles it is often only the mouth muscles that move but, as humans we often don’t spot the lack of movement around the eyes.

He adds, “An objective way of analyzing whether or not a smile is true could help us develop improved interactions (互动) between computers and humans. It could also be important to scientists aiming to gain more understanding into human behavior and emotion.”

1.Why is it hard for humans to recognize a false smile?

A.Humans are good at hiding their smiles.

B.The relevant details are hard to catch for our eyes.

C.Humans often put on too many facial expressions.

D.Techniques for analyzing facial expressions are hard to develop.

2.What do the researchers find by the software?

A.People usually use two main sets of muscles when smiling.

B.True smiles produce more muscle movement around eyes.

C.Mouths and cheeks move the same for true and false smiles.

D.True smiles are a powerful way of signaling positive emotions.

3.What can we infer from Professor Hassan Ugail?

A.There are different sets of muscles on every human’s face.

B.The software can improve humans’ behavior and emotion.

C.Humans can spot the movement around the eyes in true smiles.

D.The interactions between computers and humans remain to be improved.

4.What is the best title for the text?

A.Eyes Can Smile

B.Smiles Can Show One's Personality

C.More Smiles, Longer lives

D.True Smiles, False Movements

Scientists at the University of Oxford have developed new artificial intelligence(AI) software to recognize and follow up the faces of chimpanzees(黑猩猩)in the wild. The new software will allow researchers and wildlife conservationists to significantly cut back on time spent analyzing videos, according to the new paper published in Science Advances.

For species(物种)like chimpanzees, which have complex social lives and live for many years，getting photos of their behavior taken from short-term field research can only tell us so much，” says Dan Schofield， researcher and DPhil student at Oxford University’s Private Models Lab, School of Anthropology. “By taking advantage of the power of machine learning to unlock large video files , it makes it possible to measure behavior over the long term. ’’

The computer model was trained using over 10 million images(影像):from Kyoto University s Primate Research Institute(PRI) video files of wild chimpanzees in Guinea,West Africa. The new software is the first to continuously track and recognize individual a wide range of poses, performing with high accuracy in difficult conditions such as low lighting and poor image quality.

“Access to this large video file has allowed us to use deep neural networks to train models to a degree that was previously not possible,” says Arsha Nagrad, co-auther of the study and DPhil student at the Department of Engineer Science ,University of Oxford .” Additionally, our new software differs from previous primate face recognition software in that it can be applied to videos with limited manual intervention(人工干预)，saving hours of time. ”

The technology can be potentially used to monitor species for conservation Although the present application focuses on chimpanzees, the AI software provided will be applied to other species, and help drive the adoption of AI systems to solve(解决)a range of problems in the wildlife sciences.

1.What is the purpose of developing the new soft?

A.To save wildlife researchers’ time spent in the labs.

B.To keep track of wildlife conservationists' behaviors.

C.To protect chimpanzees and help them to live longer .

D.To recognize and track the faces of wild chimpanzees.

2.What does the underlined word “it” in paragraph 2 refer to?

A.Getting photos. B.Analyzing videos.

C.A powerful machine D.The new AI software.

3.What does paragraph 4 mainly talk about?

A.The working principle of the new software. B.Some limitations of using the new software.

C.The unique advantages of the new software. D.Controversial attitudes to the new software.

4.What can be known from the last paragraph?

A.Technology advance is the final goal of science

B.The new software won’t just be applied to chimpanzees.

C.AI systems are widely used in the wildlife sciences.

D.The application of the new technology isn’t easy.

“Access to this large video file has allowed us to use the newest deep neural networks to train models at a scale that was previously not possible,” says Arsha Nagrani, co-author of the study and DPhil student at the Department of Engineering Science, University of Oxford. “Additionally, our new software differs from previous primate face recognition software in that it can be applied to raw videos with limited manual intervention (人工干预) or pre-processing, saving hours of time.”

The technology has potential for many uses, such as monitoring species for conservation. Although the present application focused on chimpanzees, the software provided could be applied to other species, and help drive the adoption of AI systems to solve a range of problems in the wildlife sciences.
