The programme analyses the pixels to determine the nutritional information in the food and relies on image-processing technology to discover the items in the photo. For improvement, the app allows the user to correct it. Google are also looking into a dietary tool to give users an estimate of how much energy they need to burn off to get rid of the calories.
The programme does not only analyse what food is on the plate but how much, determining a more accurate calorie count. The app is currently in development.
