Even if electronic devices widely occupy our daily lives, human-machine interaction still lacks intuition.Researchers intend to resolve these shortcomings by augmenting traditional systems with aspects of human-human interaction and consider human emotion, behavior, and intention.This publication focuses on one aspect of the challenge: recognizing facial expressions.Our approach achieves real-time performance and provides robustness for realworld applicability.This computer vision task comprises of various phases for which it exploits model-based techniques that accurately localize facial features, seamlessly track them through image sequences, and finally infer facial expressions visible.We specifically adapt state-of-the-art techniques to each of these challenging phases.Our system has been successfully presented to industrial, political, and scientific audience in various events.
