It is a boimetric based App,which is gradually evolving in the universal boimetric solution with a virtually zero effort from the user end when compared with other boimetric options.
3. Traditionally, student’s attendances are taken manually by using
attendance sheet given by the faculty in class, which is a time
consuming event.
Moreover, it is very difficult to verify one by one student in a large
classroom environment with distributed branches whether the
authenticated students are actually responding or not.
FACE RECOGNITION technology is gradually evolving to a
universal biometric solution since it requires virtually zero effort
from the user end while compared with other biometric options. It is
accurate and allows for high enrolment and verification rates.

5. A facial recognition is a computer
application for automatically identifying or
verifying a person from a digital image or a
video frame from a video source.
One of the ways to do this is by comparing
selected facial features from the image and a
facial database.

6. The implementation of face recognition
technology includes the following three stages :
Image acquisition.
Image processing.
Face image classification and decision making.

8. Facial-scan technology can acquire faces from
almost any static camera or video system that
generates images of sufficient quality and
resolution.
High-quality enrolment is essential to eventual
verification and identification enrolment images
define the facial characteristics to be used in all
future authentication events.

10. Images are cropped and colour images are
normally converted to black and white in order to
facilitate initial comparisons based on gray scale
characteristics.
First the presence of faces or face in a scene must
be detected. Once the face is detected, it must be
localized and Normalization process may be
required to bring the dimensions of the live facial
sample in alignment with the one on the
template. 10
11. All facial-scan systems attempt to match visible
facial features in a fashion similar to the way
people recognize one another.
The features most often utilized in facial-scan
systems are those least likely to change
significantly over time: upper ridges of the eye
sockets, areas around the cheekbones, sides of the
mouth, nose shape, and the position of major
features relative to each other.
11
12. Every face has atleast 80 distinguishable parts
called nodal points.
12
13. Here are few nodal points below :
- Distance between the eyes
- Width of the nose
- Depth of eye sockets
- Structure of the cheek bone
- Length of jaw line

A general face recognition software conducts a comparison of
these parameters to the images in its database.
Depending upon the matches found, it determines the result.
This technique is known as feature based matching and it is the
most basic method of facial recognition.
15. Primary application being used in classrooms to
take the attendance of the students.
Decrease the false attendance.
Security/Counterterrorism: Access control,
comparing surveillance images to know
terrorist.
ATM: The software is able to quickly verify a
customer’s face.
Healthcare: Minimize fraud by verifying
identity.
