Personal Verification/Identification via Analysis of the Peripheral ECG Leads: Influence of the Personal Health Status on the Accuracy

Figure 2

Influence of the threshold for , , , and on the person verification accuracy: (a) Se_verification (I + II) = (( + )/2); Sp_verification (I + II) = (( + )/2). (b) Se_verification (I + II + PCA) = (( + + )/3); Sp_verification (I + II + PCA) = (( + + )/3). (c) Se_verification (max(, , )) = (max(, , )); Sp_verification (max(, , )) = (max(, , )). (d) Se_verification (min(, , )) = (min(, , )); Sp_verification (min(, , )) = (min(, , )). (e) ROC curves and calculated AUC for classification based on + , + + , min(, , ), and max(, , ). The solid circles mark the optimal solutions.
