Detection of Genuine and Posed Facial Expressions of Emotion: A Review
Facial expressions of emotion play an important role in human social
interactions. However, posed acting is not always the same as genuine feeling.
Therefore, the credibility assessment of facial expressions, namely, the
discrimination of genuine (spontaneous) expressions from
posed(deliberate/volitional/deceptive) ones, is a crucial yet challenging task
in facial expression understanding. Rapid progress has been made in recent
years for automatic detection of genuine and posed facial expressions. This
paper presents a general review of the relevant research, including several
spontaneous vs. posed (SVP) facial expression databases and various computer
vision based detection methods. In addition, a variety of factors that will
influence the performance of SVP detection methods are discussed along with
open issues and technical challenges
