What is the main idea of the news item?
Experts say that automatic face recognition systems, in which a computer attempts to recognize an individual by checking his or her face against thousands of images stored in a database, are gaining in popularity, but are not very reliable.
There won’t be a match if the person’s face is not contained in the database, or a match may be overlooked if a picture that is in the database looks sufficiently different than the individual standing in front of the system’s electronic eye.
Experts say that’s because the stored photograph may be several years old and bear little resemblance to the individual, or the pose or light may be different.
Psychologist Rob Jenkins of the University of Glascow and his colleague Mike Burton believe they solved the problem.
They randomly gathered 20 images of 25 famous male celebrities on the Internet and fed the photos into a face recognition system that had a database of 31-thousand photos of famous faces.
The recognition system accurately identified the individuals, about half of the time.

B、The automatic recognition of celebrities.
