2.3 Face Recognition Types
2D System In the past [4], facial recognition programs
depended on two dimension (2D) picture to compare it
with the image sorted in the data base, but these programs
did not succeed only if the person is looking just to the
camera. Of course anyone suspect will be warned that
he/she will see a camera in place, and here lies the
problem where this fails by depending on the 2D system.
Beside, the additional changes in the environment
surrounding the person, such as light will produce images
the computer cannot have in the corresponding memory,
also the changes in the same person can cause a system
failure in face recognition [5, 6].
3D System Modern system for face recognition based on
the pattern of three-dimensional (3D) [8], where the
special cameras will captured images of three-dimensional
views of the suspected person, and using the special main
features of each face that are not changed significantly
