Face recognition system will tell you liked

Dutch researchers Tao Jevers (Theo Gevers) and Nicu Sebe (Nicu Sebe), known for their deciphering Mona Lisa smile, created a face recognition system that can assess the level of human happiness. Scientists working with the manufacturer of multi-ethnic goods Unilever, created an algorithm for tracking facial features, which translates the video into three-dimensional space. Then the three-dimensional picture serves to determine the level of pleasure.
The test system was conducted among 300 women from eight European countries. The system checked videotapes where women ate five different foods: vanilla ice cream, chocolate, breadsticks, yogurt, and apples. As expected, scientists found that women liked ice cream and chocolate more than yogurts and apples - the latter even caused a “sadness” among 28% of those who participated in the testing system.
