Abstract
There is provided a method of computing head pose of a subject in a 2D image, comprising: analyzing the image to identify a first nostril, a second nostril, a medial eye substructure of a first and a second eye, and a lateral eye substructure of the first and the second eye, computing a median nostril point between the first and second nostrils, computing a horizontal line that connects the lateral eye substructures of the first and second eyes, computing a vertical axis line that is orthogonal to the horizontal line and passes through a median eye point between the medial eye substructures of the first and second eyes, computing an offset distance between the vertical axis line and the median nostril point, and computing an indication of an estimated yaw angle of the head pose of the subject based on the offset distance.
