Abstract
The present disclosure relates to systems and methods for automated identification of presence of a facial action from sequential images. The systems and methods may obtain a plurality of sequential candidate image frames containing a facial object. Each of the plurality of candidate image frames may include a plurality of feature points associated with an eye of the facial object. For each of the plurality of sequential candidate image frames, the systems and methods may determine an area of a polygon based on the plurality of feature points. The systems and methods may determine a distance associated with the eye of the facial object. The systems and methods may determine an action parameter based on the area and the distance. The systems and methods may identify the presence of a blink action in response to that the action parameters satisfy one or more preset conditions.
