Face recognition technology

  1. 1. FACE RECOGNITION TECHNOLOGY T.DIVYA ROLL NO.:08RG1A0481 E.C.E
  2. 2. Topics Of Discussion Why FRT? How to implement? Applications Opposition Future of face recognition
  3. 3. Why only Face Recognition? It is accurate No need of expert Passive identification in one to many environment
  4. 4. Comparison types Verification accomplished by system performing a “one-to-many” search Identification accomplished by the system performing a “one-to-one” search
  5. 5. Components involved Enrolment module Data base Identification module
  6. 6. FIVE STEP PROCESS (STEP 1)ACQUIRING THE IMAGE OF AN INDIVIDUALS FACE2 WAYS TO AQUIRE IMAGE1)Digitally scan an existing photograph2)Acquire a live picture of a subject
  7. 7. FIVE STEP PROCESS (STEP 2)LOCATE IMAGE OF FACE -software is used to locate the faces in the image that has been obtained
  8. 8. FIVE STEP PROCESS (STEP 3)ANALYSIS OF FACIAL IMAGE -software measures face according to is peaks and valleys (nodal points) -focuses on the inner region of the face known as the “golden triangle” -nodal points are used to make a face print
  9. 9. FIVE STEP PROCESS (STEP 4)COMPARISON -the face print created by the software is compared to all face prints the system has stored in its database.
  10. 10. FIVE STEP PROCESS (STEP 5)MATCH OR NO MATCH software decides whether or not any comparisons from step 4 are close enough to declare a possible match
  11. 11. FINAL STEP THE HUMAN OPERATOR
  12. 12. Applications Residential security Banking using ATM Voter identification Immigration …………………….
  13. 13. Not Everyone Loves Face Recognition Critics say it produces too many false positives Invasion of privacy To easy to misuse for wrong purposes Technology is not accurate enough given the current technology and algorithms
  14. 14. Future Of Face Recognition Some consider the problem impossible No standard way of approaching the problem Advancements in hardware and software Slow integration into society in limited environments Very large potential market
  15. 15. Thank you ?
