  1. Ear Biometric FatemehArbab Department of Computer Science University of Calgary farbab@ucalgary.ca Winter 2009

  2. Out line Introduction Anatomy of Ear Innarelli system Burge and Burger PCA Hurley, Nixon and Carter Akkermans, Kenvenaar and Schobben Conclusion

  3. Introduction • Why Ear? • Stable structure • Predictable change with age • It’s fixed position • Collection hygiene issues • Unlikely to cause anxiety

  4. Anatomy of Ear

  5. Innarelli System • Used for forensic in 1949, USA • Specified distances • Race • Sex

  6. Burge and Burger Neighbor Graph Matching, 1998 Ear print VoronoiDiagram Neighbor Graph

  7. Burge and Burger • Improving FAR Still is not practical! • Ear description is unstable • Detected edges were occluded parts rather than surface discontinuities • Occlusion with hair • Thermogram

  8. Principle Component Analysis Basis elements in a Vector space

  9. Principle Component Analysis Implementation Recognition rate of 98.4% on a data set of 252 ear images

  10. Hurley, Nixon and Carter Force Field Transform, 2005

  11. Hurley, Nixon and Carter Force Field Transforms: Invertible transforms

  12. Hurley, Nixon and Carter • Sample • Promising results on small database

  13. Akkermans, Kenvenaar and Schobben • Acoustic Ear Recognition, 2005 • Correlation of emitted and reflected wave • Applicable on headphones or modified mobile phones • 31 and 17 samples, respectively

  14. Conclusion Summary

  15. What else… • Sample of 3D ear biometric • Iterative Closest Point
