Face Recognition Technology

  1. 1. By P. Shashidhar Reddy
  2. 2. What do you mean by Face Recognition Technology??? A technology Which is used to automatically identify or verify a person from a Digital Image or a Video Frame from Video Source One of the way to do this is by comparing selected Facial Features from the Image and the Facial Database
  3. 3. What is Behind Face Recognition???  How is it Possible??
  4. 4. Biometrics A biometric is a unique, measurable characteristic of a human being that can be used to automatically recognize an individual or verify an individual’s identity
  5. 5. Biometrics can be measure in both Physiological and Behavioral Characteristics Physiological Characteristics: 1. Finger- Scan 2. Iris Scan 3. Retina Scan 4. Hand Scan 5. Facial Recognition 80 landmarks on a human face. oDistance between eyes oWidth of the nose oDepth of the eye socket oCheekbones oJaw lines oChin
  6. 6. Behavioral Characteristics: Behavioral biometrics (based on measurements and data derived from an action) include: 1. Voice Scan 2. Signature Scan 3. Keystroke
  7. 7. Why we choose face recognition over other biometric?  It requires no physical interaction on behalf of the user.  It does not require an expert to interpret the comparison result.  Identify a particular person from large crowd  Verification of credit card, personal ID, passport
  8. 8. What is behind this Technology  The heart of this facial recognition system is the Local Feature Analysis (LFA) algorithm.  This is the mathematical technique the system uses to encode faces  The system maps the face and creates a face print, a unique numerical code for that face.  Once the system has stored a face print, it can compare it to the thousands or millions of face prints stored in a database.
  9. 9. Face recognition: Procedure Input face image(Capture) Face feature extraction Feature Matching Decision maker Output result
  10. 10. 1. Eigen face or PCA (Principal Component Analysis) 2. EBGM -Elastic Bunch Graph Method.-2D Image 3. 3D Face Recognition Method.-3D Image Face Feature Extraction Methods
  11. 11. Access Control Products Access Control into Bank Kiosk Lyon Airport, France New Face Reader with LCD Face Reader with mirror -ATM
  12. 12. Advantages:  Convenience and social acceptability  Easy to use  Inexpensive
  13. 13. Disadvantages:  Face recognition systems can’t tell the difference between identical twins
  14. 14. Future of Face Recognition  Billboard with face recognition –Advertising  Face base Retailing-(Shopping) retail stores, restaurants, movie theaters, car rental companies, hotels. (You Can pay the bills using your face)  Recognition Twins  More High Speed accessing of Database
  15. 15. 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
