Face Recognition with Time-Varying Expressions for Homeland Security Applications
Fig-1: All images are registered using selected control points, related to the two eyes and nose. Each pair of control points is determined using normalized cross-correlation. The images are then registered using a linear transform. The image above shows results of image registration. (a) Corresponding point selection (b) Unregistered (input image); (c) Base image; (d) Registered image. |
