Frame-level ground-truth for facial actions was obtained using the Facial Action Coding System.
About
The work promotes the exploration of 3D spatiotemporal features in subtle facial expression, a better understanding of the relation between pose and motion dynamics in facial action units, and a deeper understanding of naturally occurring facial action.
Key Benefits
• Induced emotional responses were spontaneous instead of posed, making the database more relevant for research • Facial features were tracked in both 2D and 3D domains using person • specific and generic approaches • Database includes a diverse array of participants
