FACE RECOGNITION TECHNOLOGY
[attachment=16194]
INTRODUCTION
Complex and largely software based technique
Analyze unique shape, pattern &positioning of facial features
It compare scans to records stored in central or local database or even on a smart card
WHAT IS BIOMETRICS?
It is a unique measurable characteristics of a human being
Used to automatically recognize an individual’s identity
Two types 1.physiological &
2. behavioral characteristics include
A “biometric system” refers to integrated hardware and software used to conduct biometic identification
FACE RECOGNITION
Two types of comparison in face recognition
1.Verification- The system compare the given individual with who that individual says they are.
2 .Identification-The system compares a given individual to all the other individuals in the database and gives a ranked list of matches.
ADVANTAGE
Convenience and social acceptability
Easy to use
Inexpensive biometric
DISADVANTAGE
Face recognition systems can’t tell the difference between identical twins
CONCLUSION
Face recognition technologies have been
associated generally with very costly top secure
applications. Today the core technologies have
evolved and the cost of equipments is going down
dramatically due to the integration and the
increasing processing power. Certain applications
of face recognition technology are now cost
effective ,reliable and highly accurate. As a result
there are no technological or financial barriers for
stepping from the pilot project to widespread
deployment
