3. Face Recognition Technology is a biometric
system of identification. It is very helpful for many
security applications. The main uses of face recognition
is for time attendance, access control and visitor
management. Each human being has different facial
features like peaks, valleys and different peaks in their
face. These landmarks are defined as nodal points. An
approximate number of 80 nodal points present in one
human being. Distance between the eyes, length of the
jaw line, shape of the cheekbones, depth of the eye
sockets and width of the nose are considered for the
measurement. By using the facial identification we can
avoid the intrusion or delay.
4. The person’s face is captured by using a digital
video camera. And it measures all the necessary
features like distance between the eyes, length of the
jaw line, and shape of the cheekbones, depth of the
eye sockets and width of the nose. The captured
image is compared with the image stored in the
database. After capturing the image a template is
created by extracting a unique data. New image is
compared with it. And check if it matches with the
new image. The person must stand 2 feet back from
camera. Normally the system takes five seconds to
take the decision. Facial recognition system is very
useful for averting terrorist crimes and also it is
widely used in some of the law enforcement sections.
5. For user verification systems in computer
networks and banking sections it is widely used. For
the taking the time and attendance of employees it is
very fast and safety method. It is very easy to use and
install. It has less cost and very efficient method. It
can control the access. There is no need to carry cards
and keys. Also it is used to keep the track of visitors.
In facial recognition process the picture is cut into
smaller blocks. Then by using some algorithms
mathematical measures are taken. So we can identify
the very small differences in identical twins also.
