There are 64 "Action Units", each with a name, the muscle groups involved in obtaining that facial expression starting from a neutral, relaxed face and a picture showing that facial expression, as it can be seen in Figure 1.
Matthews, "The extended Cohn-Kanade dataset (CK+): a complete dataset for action unit and emotion-specified expression," in Proceedings of the IEEE Computer Society Conference on Computer Vision and Pattern Recognition (CVPRW '10), pp.
The authors used six efficient Action Units (AUs) as inputs to the neural classifier as compared to the usage of 60 inputs of x and y coordinates formed by 30 facial fiducial points.
Thus, each label for an elementary unit of meaning grouped together the action and the meaningful part of it and was then called an "action unit." After identifying an action unit, we isolated the Representamen (i.e., what the athletes were focused on) and the Interpretant (i.e., what they knew, understood or felt about the situation).
Nineteen Taleban, disguised in military fatigues, entered the Rapid Action Unit 5 of the Ghazni Police at 5.30am while 14 other men, armed to the teeth, broke into the compound of the Afghan National Directorate of Security (Intelligence).
Finally, for each action unit, we used a binary support vector machine (SVM) for context-independent classification.
Facial Action Coding System (FACS) [6-9] was developed by Ekman and Friesen in 1978 to objectively measure facial activity for behavioral science investigations of the face, which provided an objective description of facial signals in terms of component motions, or "facial actions" They defined 46 action units (AUs), as shown in Table 1, and each action unit was constituted by one or several pieces muscles, to correspond to each independent motion of the face, and they combined different action units to show different facial expressions.
An Action Unit can be totally uninvolved or it can be involved to a maximum level i.e.
Iran strongly denied any involvement in what the United States said was a plot originating with the Quds Force, Iran's covert external action unit, to kill the ambassador by hiring assassins from a Mexican drug cartel for $1.5 million.

Vic, whose family are from Glasgow, retired from doing stunts himself in the late Eighties but, as stunt co-ordinator and action unit director, has crafted some of the most incredible set piece moments in movies such as War of the Worlds, GoldenEye, and Terminator 2.
Before the Second World War Lain had created the organisation Gwenn-ha-Du as a Breton nationalist direct action unit modelled on the IRA.
