21 AQUIRING DATA (Enrollment)

22 AQUIRING DATA Thinning a fingerprint Let A(P) be the number of 01 patters in the order set P2 … P9 Let B(P) be the number of non-zero neighbors of P Do until image is stable (i.e. no changes made) Sub-iteration 1: Delete P from image if: a) 2 ≤ B(P) ≤ 6 b) A(P) = 1 c) P2 * P4 * P6 = 1 d) P4 * P6 * P8 = 1 Sub-iteration 2: Delete P from image if: a) and b) from above c') P2 * P4 * P8 = 1 d') P2 * P6 * P8 = 1
