Abstract
A method for identifying a body motion includes receiving a series of images including a visual presentation of a human face from the image capture device. The series of images may form an image sequence. Each of the series of images may have a previous image or a next image in the image sequence. The method also includes, for each of the series of images, determining a plurality of characteristic points on the human face, determining positions of the plurality of characteristic points on the human face, and determining an asymmetry value based on the positions of the plurality of characteristic points. The method further includes identifying a head-shaking movement of the human face based on the asymmetry values of the series of images.
