What is Face Recognition
n An advance biometric identification technique
Fundamentals
step 1 ) face detection
In this step, the system will check is input image a face or not?
face detection is a computer technology that identifies human faces in digital images. It detects human faces which might then be used for recognizing a particular face. This technology is being used in a variety of applications nowadays.
Application
Face Recognition Access Control System
Face Recognition access control system is called FaceGate, Whenever one wishes to access a building, FaceGate verifies the person’s entry code or card, then compares his face with its stored “key.” It registers him as being authorized and allows him to enter the building. Access is denied to anyone whose face does not match.
Fundamentals
step 3 ) recognization process
After step2, the extracted feature of the input face is matched against those faces in the database; just like this pictuer, it outputs the result when a match is found.
Face recognition-based systems in these applications can achieve high accuracy without much cooperation from the users.

step 2 ) feature extraction for trainesame time for input image
Feature extraction can provide effective information .Like those pictures, a birthmark under the right eye is useful to distinguish that they are one person.
