Presentation Transcript

  1. Facial Recognition Systems By Derek Ciocca

  2. Parts of the system • Improving Accuracy • Current and future uses

  3. Parts of the System • The camera to take the pictures • The database to retrieve photos • The ‘algorithm’ to compare the current photo to past photos

  4. Basic theory • Distinctive facial features measured • Distance between eyes • Width of nose • Length of the jaw-line • Approx. 80 different points

  5. Problems with 2D Pictures • Very sensitive to light & shadow • Picture had to be straight on • Sensitive to changes in facial expression

  6. 3D facial recognition

  7. Surface Texture Analysis • Measures color and texture of skin • More tolerant to changes in facial expression, hair, and accessories • Improvement of 20-25%

  8. Current & Future Uses • Security • Used at Super Bowl XXXV • Airports • ATM verification (future) • Advertisements
