Computers can now guess our age
“So is this software successful at guessing our age? “‘Human faces do convey a significant amount of information, however, and provide important visual cues for estimating age,’ Huang said. ‘Facial attributes, such as expression, gender and ethnic origin, play a crucial role in our image analysis.’ Consisting of three modules — face detection, discriminative manifold learning, and multiple linear regression — the researchers’ age-estimation software was trained on a database containing photos of 1,600 faces. The software can estimate ages from 1 year to 93 years. The software’s accuracy ranges from about 50 percent when estimating ages to within 5 years, to more than 80 percent when estimating ages to within 10 years. The accuracy can be improved by additional training on larger databases of faces, Huang said.”"
