Expensive fruit will help you remember the number for expensive fruit
German researchers have developed intelligent self-service scales for supermarkets, able to recognize fruit or vegetables placed on them. The scales automatically recognize the item being weighed and ask the customer to choose between only those icons that are relevant, such as various kinds of tomatoes. The scales are equipped with a camera and an image evaluation algorithm that compares the image of the item on the scale with images stored in its database. Store managers can add items to the database. The scales are now being tested in about 300 supermarkets across Europe.
