Biometrics & Security Tutorial 11
1 (a) Why multi-biometrics? (P13: 3-6)
1 (b) What kinds of fusions we can take?
1 (c) Please explain three fusion modes in P13: 12.
1 (d) What difference between biometric uni-modal and biometric multi-modal? (P13: 13-14)
2. There are four fusion levels defined in P13: 15. Could you give the corresponding structure of each fusion level?
3. Some fusion functions are given in both matching and decision level (P13: 25; 32-34). Please understand their math definitions.
Fusion = Score1 + Score2 or = Score1 x Score2 or = Max (Score1, Score2) or = ……
