Aff-Wild Database

In the context of Human Computer Interaction(HCI), building an automatic system to recognize affect of human facial expression in real-world condition is very crucial to make machine interact with a man in a naturalistic way. However, existing databases of facial emotion usually contain facial expression in the limited scenario under well-controlled condition. Aff-Wild is currently the largest database consisting of spontaneous facial expression in the wild annotated with valence and arousal value.
