Affect Analysis in-the-wild: Valence-Arousal, Expressions, Action Units and a Unified Framework

Understand

Affect recognition based on subjects' facial expressions has been a topic of major research in the attempt to generate machines that can understand the way subjects feel, act and react.

• In the past, due to the unavailability of large amounts of data captured in real-life situations, research has mainly focused on controlled environments.
• However, recently, social media and platforms have been widely used.
• Moreover, deep learning has emerged as a means to solve visual analysis and recognition problems.
