Measuring Biometric Sample Quality in terms of Biometric Feature Information in Iris Images
Figure 8
Fractional BI loss as a function of degradation level for 10 different (a) Gaussian blur levels, (b) white Gaussian noise variances, (c) salt and Pepper noise densities, (d) speckle noise variances where the (x-axis) shows a gradual increase in the noise and blur levels. (e) shows the amount of BI loss (unitless) as a function of noise variance, (f) shows the amount of BI loss (unitless) as a function of noise and blur degradation levels.
