Measuring Biometric Sample Quality in terms of Biometric Feature Information in Iris Images

Figure 4

Biometric ICA iris feature information computed for 327 iris features where features are extracted using the Log-Gabor filter from the iris region at a constant angle/varying radius. The 𝑦 -axis represents the biometric information for each feature (in bits), and the 𝑥 -axis is the feature number. The standard deviation is also plotted at the bottom of each graph.
