A facial expression database is a collection of images or video clips with facial expressions of a range of emotions. Well-annotated ( emotion -tagged) media content of facial behavior is essential for training, testing, and validation of algorithms for the development of expression recognition systems .
The development of FACS tools for different species allows the objective and anatomical study of facial expressions in communicative and emotional contexts. Furthermore, a cross-species analysis of facial expressions can help to answer interesting questions, such as which emotions are uniquely human. [21]
Eye contact and facial expressions provide important social and emotional information. People, perhaps without consciously doing so, search other's eyes and faces for positive or negative mood signs. In some contexts, the meeting of eyes arouses strong emotions.

Kate Middleton looked somber during her recent return to royal duties, but I noticed something interesting about her facial expressions. Over the weekend, the Princess of Wales attended the ...
Looping is where facial expressions can elicit involuntary behavior. In the research motor mimicry there shows neurons that pick up on facial expressions and communicate with motor neurons responsible for muscles in the face to display the same facial expression. Thus displaying a smile may elicit a micro expression of a smile on someone who is ...
