ABSTRACT:
A method of and system for determining the angular orientation of an object, such as a person's head. In one aspect, a plurality of images of the object is obtained. Values are assigned to a plurality of positions in a polar plot using data from the images. A centroid is computed based on the assigned values. An angle of the centroid with respect to an origin of the polar plot indicates the angular orientation of the object.
