1Scientists believe they have found a new use for facial recognition technology:saving large ocean animals known as seals.Researchers at Colgate University in the US state of New York have developed SealNet.The system is a database of seal faces created by taking pictures of many harbor seals in Maine's Casco Bay.

2The research team found the tool's accuracy in identifying the mammals was close to 100 percent.The researchers are working on increasing the size of their database to make it available to other scientists,said Krista Ingram,who is a biology professor at Colgate and a team member.

3Increasing the database to include rare species such as Mediterranean monk seals and Hawaiian monk seals could help save those species.Creating a list of seal faces and using machine learning to identify them could also help scientists know where in the ocean seals are.For marine mammals that move around a lot and are hard to photograph in the water, we need to be able to identify individuals,Ingram said.

4SealNet is designed to identify the face in a picture.It recognizes the seal's face based on information related to the eyes and nose shape, as it would recognize a human.A similar tool called PrimNet, which is used on primates (靈長類), had been used on seals earlier, but SealNet performed better, the Colgate researchers said.Seals and other ocean mammals have long been studied using satellite technology.Using artificial intelligence to study them is a way to bring conservation into the 21st century.

5Facial recognition technology could provide valuable data, said Michelle Berger, an associate scientist at the Shaw Institute in Maine.Berger was not involved in the SealNet research.“Once the system is perfected, I can picture lots of interesting environmental uses for it,”Berger said.“If it could recognize seals, and recognize them from year to year,that would give us lots of information about how much they move from site to site.”
