Microsoft is testing out an amazing website called How-Old.net, which guesses how old you are from a single photo. It uses facial-recognition technology to predict the age and sex of people pictured in photographs submitted to the site.
Let Microsoft ‘Guess’ If You Have A Twin. This service determines if two individuals resemble each other through the photos uploaded to the site. TwinsOrNot.net uses facial recognition technology to analyse photo submissions. Individuals are required to submit to the site two different images, which will then be given a score to see how alike they are to each other.
