CNN.com posted a story today that describes computer-based emotion recognition software that was used to analyze the famous smile of Leonardo Da Vinci’s Mona Lisa painting. The story refers to a recent British weekly journal, “New Scientist“, report about the software developed by Nicu Sebe (University of Amsterdam) and researchers at the Beckman Institute, University of Illinois Urbana-Champaign. The software examines key facial features (curvature of the lips, crinkles around the eyes, etc) to produce an analysis of the subject using six basic emotions (happiness, surprise, sadness, fear, anger, and disgust). The results said that Mona Lisa was 83% happy, 9% disgusted, 6% fearful, and 2% angry.
