Figure 15From: Biometric quality: a review of fingerprint, iris, and faceRelation between match scores obtained from a commercial iris matcher and various quality metrics. Relation between match scores obtained from a commercial iris matcher (z-axis) and various quality metrics [(a) SE, (b) ES, (c) A, (d) B, (e) Z, (f) DF, (g) MB, (h) O, (i) I, (j) SR, (k) PC, (l) Q, (m) BR] for genuine (green) and imposter (red) match pairs. The x-axis pertains to gallery quality while y-axis pertains to probe quality. The scatterplot indicates that ES, A, B, Z, SR, PC, and BR quality metrics can characterize genuine scores of match pairs. However, DF, O, I, and Q are unable to characterize genuine match scores.Back to article page
