• 1 (c) List the differences between the Raul Sanchez-Reillo’s approach and A.K. Jain’s approach. (P9:10-21)
• 1 (e) Understand Gaussian Mixture Modelling (GMM), Pre-processing and feature extraction (P9:22-23)
• 2. There are 31 features of hand geometry in Raul Sanchez-Reillo’s approach. Please try to list them. (P9:12-18)
• 3. As a general 3D hand geometry approach introduced in P9:5-9, there are 14 features defined. The matching score: Euclidean distance can be defined by
•
• Please try to make a figure like P8:37 (Euclidean Dis. – Percent).

• 4. In A.K. Jain’s approach, there are sixteen axes along which feature values are computed. Please try to define the corresponding hand features. (P9:21)
• Let F = (f1; f2; … ; fd) represent the d -dimensional feature vector
• (65 53 59 52 62 47 47 45 255 333 253 287 243 149 )
• 5. There are five steps defined by a finger recognition system (P9: 32-36). What kinds of features are used in this system?
• (joint line) • Do you have any idea to compare two
templates exactly? • (shift to the best match)• Based on the given input image in Q3
(Tutorial 4), we project it to the i-axis. What is its one-dimensional data? (17, 24, 43, 28, 45)
