Effect of varying the threshold ($\tau$) on the classification confidence level. Classification is obtained using LBP and first-order statistics with SVM. (a) Boxplot of the class-specific accuracy-rate (${\mathrm{rec}}_{\mathrm{class}}$) for different $\tau$. The percentage of confident patches for each $\tau$ is reported above each boxplot. $\tau =0$ refers to classification without confidence estimation. (b) Normalized confusion matrix for $\tau =0.9$. The number of patches for each class is reported in parenthesis.
