Abstract
In one embodiment, the present invention includes a method to use active contours to detect image boundaries of a first view and a second view of a human face, and mark a first set of fiducial points on the first view and a second set of fiducial points on the second view. Using the fiducial points, feature vectors may be calculated and stored in a database for later comparison with a query image.
