with time , such as eye hole, the distance between the
eyes, nose shape and others mentioned above. These
features are a source of information for a facial recognition
system as the changes in the lighting or surrounding
environmental conditions do not affect these
measurements, for example: can operate these systems in
any lighting conditions even if the place was dark and
even if the person is not in the face of camera.
2.4 3D Face Recognition
How 3D Procedure Work: The use of depth and focus of
the face that does not affect the change in lighting is
known as three-dimensional face recognition system. The
software system that relay on three-dimensional technique
with a series of steps to eventually be able to perform a
face recognition procedure. We can divide the whole
process by the following steps. Steps involve in the face
recognition system are: (fig 1)
Fig. 1 the steps of 3D face recognition system.
1) Detection: Capture a digital image by a two
dimensional digital camera or even using a video camera.
