Solutions for Behavioural Research
FaceReader
Overview
FaceReader automatically analyses facial expressions, providing an objective measurement of emotions. It classifies the six basic expressions: happy, sad, angry, surprised, scared and disgusted, as well as recognising 'contempt' and a 'neutral' state. Attitudes such as ‘interest’, ‘boredom’ and ‘confusion’ can also be automatically measured and recent work even allows researchers to explore whether a person is being sincere (for example when they smile).
FaceReader also logs: valence, arousal, gaze direction, head orientation, age, gender, ethnicity and the presence of facial hair and glasses.
Free 30 day trial available to evaluate the software and support grant bids.
How it Works
Using still images, video clips or a live feed, FaceReader classifies the face through:
- Face Finding – automatically locates the face for all ethnicities and ages over 3 years.
- Face Modelling – an artificial face model is applied using the Active Appearance Model, describing over 500 key points and texture. This is used in combination with the Deep Face algorithm to ensure classification even when there is a temporary partial occlusion of the face.
- Face Classification – output provided, with frame-by-frame accuracy.
