A scientist goes to a forest to study monkeys. He or she wants to study their habits. But the first problem is: how to know who’s who?
In the past, scientists had to make marks on each of the animals to tell them apart(分辨). But in the future, they may have a much easier way, thanks to facial recognition technology(面部识别技术).
A research team from China’s Northwest University is using facial recognition technology to recognize thousands of monkeys that live on Qinling Mountain in Shanxi province. It’s quite like human facial recognition and it uses the facial features(特点) of the monkeys to create a database(数据库) that includes every monkey. “When the system is fully developed in the future, we can connect it with cameras set up in the mountains. The system will recognize the monkeys, name them and try to understand their behavior,” said Zhang He, a member of the research team. “The recognition success rate is 94 percent.”
Compared with facial recognition technology for humans, facial recognition technology for monkeys is more complicated (复杂的) because monkeys have faces with hairs. The color of their hair causes them to blend (融入) into their environment. These factors make it harder for computers to do the job. Besides, monkeys do not work with researchers in the same way humans do. It is difficult to take high-quality pictures and videos of them, which are needed to improve the system.
